Kate Winslet

Winslet was among 175 girls to audition for Peter Jackson's psychological drama Heavenly Creatures (1994), and was cast after impressing Jackson with the intensity she brought to her part.[29] The New Zealand-based production is based on the Parker–Hulme murder case of 1954, in which Winslet played Juliet Hulme, a teenager who assists her friend, Pauline Parker (played by Melanie Lynskey), in the murder of Pauline's mother. She prepared for the part by reading the transcripts of the girls' murder trial, their letters and diaries, and interacted with their acquaintances.[30] She has said she learnt tremendously from the job.[9] Jackson filmed in the real murder locations, and the experience left Winslet traumatised.[15] She found it difficult to detach herself from her character, and said that after returning home, she often cried.[30] The film was a critical breakthrough for Winslet;[31][32] Desson Thomson, a reviewer for The Washington Post, called her "a bright-eyed ball of fire, lighting up every scene she's in".[33] Winslet recorded "Juliet's Aria" for the film's soundtrack.[34] Also that year, she appeared as Geraldine Barclay, a prospective secretary, in the Royal Exchange Theatre production of Joe Orton's farce What the Butler Saw.[35]

While promoting Heavenly Creatures in Los Angeles, Winslet auditioned for the minor part of Lucy Steele for a 1995 film adaptation of Jane Austen's novel Sense and Sensibility, written by and starring Emma Thompson. Impressed by her reading, Thompson cast her in the much larger part of the recklessly romantic teenager Marianne Dashwood.[36] The director Ang Lee wanted Winslet to play the part with grace and restraint—aspects that he felt were missing from her performance in Heavenly Creatures—and thus asked her to practise tai chi, read gothic literature, and learn to play the piano.[36] David Parkinson of Radio Times considered Winslet to be a standout among the cast, and Mick LaSalle of the San Francisco Chronicle took note of how well she had portrayed her character's growth and maturity.[37][38] The film grossed over $134 million worldwide.[39] She won the Screen Actors Guild and British Academy Film Award for Best Supporting Actress, and received nominations for the Academy Award and Golden Globe Award in the same category.[40] Also in 1995, Winslet featured in the poorly received Disney film A Kid in King Arthur's Court.[41]

Winslet had roles in two period dramas of 1996—Jude and Hamlet. As with Heavenly Creatures, her roles in these films were those of women with a "mad edge".[30] In Michael Winterbottom's Jude, based on the novel Jude the Obscure by Thomas Hardy, she played Sue Bridehead, a young woman with suffragette leanings who falls in love with her cousin, Jude (played by Christopher Eccleston). The critic Roger Ebert believed the part allowed Winslet to display her acting range, and praised her for the defiance she brought to the role.[42] After unsuccessfully auditioning for Kenneth Branagh's 1994 film Mary Shelley's Frankenstein, she was cast for the part of Ophelia, the doomed lover of the title character, in Branagh's adaptation of William Shakespeare's tragedy Hamlet.[36] Winslet, aged 20, was intimidated by the experience of performing Shakespeare with such established actors as Branagh and Julie Christie, saying the job required a level of intellect that she thought she did not possess.[30] Mike Jeffries of Empire believed that she had played the part "well beyond her years".[43] Despite the acclaim, Jude and Hamlet earned little at the box office.[44][45]

Leonardo DiCaprio (pictured) was paired opposite Winslet in Titanic (1997). A journalist for Vanity Fair labelled them "Hollywood's most iconic screen couple" since Humphrey Bogart and Ingrid Bergman.[46]

Winslet was keen on playing Rose DeWitt Bukater, a socialite aboard the ill-fated RMS Titanic, in James Cameron's epic romance Titanic (1997). Cameron was initially reluctant to cast her, preferring the likes of Claire Danes and Gwyneth Paltrow, but she pleaded with him, "You don't understand! I am Rose! I don't know why you're even seeing anyone else!"[47] Her persistence led him to give her the part.[47] Leonardo DiCaprio featured as her love interest, Jack. Titanic had a production budget of $200 million, and its arduous principal photography was held at Rosarito Beach where a replica of the ship was created.[25] Filming proved taxing for Winslet; she almost drowned, caught influenza, suffered from hypothermia, and had bruises on her arms and knees. The workload allowed her only four hours of sleep per day and she felt drained by the experience.[48][49] Writing for Newsweek, David Ansen commended Winslet for capturing her character's zeal with delicacy,[50] and Mike Clark of USA Today considered her to be the film's prime asset.[51] Against expectations, Titanic went on to become the highest-grossing film to that point, earning over $2 billion in box office receipts worldwide,[47][52] and established Winslet as a global star.[53] The film won eleven Academy Awards—tied for most for a single film—including Best Picture and earned the 22-year-old Winslet a nomination for a Best Actress in a Leading Role, making her the fourth-youngest nominee in the category at that time.[54] She also received Golden Globe and SAG nominations for Best Actress.[55][56]

Winslet did not view Titanic as a platform for bigger salaries. She avoided parts in blockbuster films in favour of independent productions that were not widely seen, believing that she "still had a lot to learn" and was unprepared to be a star.[9][19][44] She later said her decision ensured career longevity.[57] Hideous Kinky, a low-budget drama shot before the release of Titanic, was Winslet's sole film release of 1998.[58] She turned down offers to star in Shakespeare in Love (1998) and Anna and the King (1999) to do the film.[59] Based on the semi-autobiographical novel by Esther Freud, Hideous Kinky tells the story of a single British mother yearning for a new life in 1970s Morocco.[53][58] Janet Maslin of The New York Times praised Winslet's decision to follow-up Titanic with such an offbeat project, and took note of how well she had captured her character's "obliviousness and optimism".[58]

Jane Campion's psychological drama Holy Smoke! (1999) featured Winslet as an Australian woman who joins an Indian religious cult. She found the script brave and was challenged by the idea of playing an unlikeable, manipulative woman.[53][57] She learnt to speak in an Australian accent and worked closely with Campion to justify her character's vileness.[53][60] The film required her to perform explicit sex scenes with co-star Harvey Keitel, and featured a scene in which her character appears naked and urinates on herself.[53][61] David Rooney of Variety wrote, "Showing the kind of courage few young thesps would be capable of and an extraordinary range [...] from animal cunning to unhinged desperation, [Winslet] holds nothing back."[62] That same year, she voiced a fairy for the animated film Faeries,[63] and won the Grammy Award for Best Spoken Word Album for Children for narrating the short story "The Face in the Lake" for the children's audiobook Listen to the Storyteller.[64][65]

In Quills (2000), a biopic of the erratic Marquis de Sade, starring Geoffrey Rush and Joaquin Phoenix, Winslet played the supporting role of a sexually repressed laundress working in a mental asylum.[66][67] Hailing her as the "most daring actress working today", James Greenberg of Los Angeles magazine praised Winslet for "continuing to explore the bounds of sexual liberation".[68] She received a SAG Award nomination for Best Supporting Actress.[69] The following year, she played a fictitious mathematician involved in the cracking of the Enigma ciphers in Michael Apted's espionage thriller Enigma. Winslet's character was vastly expanded from a subsidiary love-interest in the novel it was based on to a prominent code-breaker in the film.[70] She was pregnant while filming, and to prevent this from showing, she wore corsets under her costume.[71]

The biopic Iris (2001) featured Winslet and Judi Dench as the novelist Iris Murdoch at different ages. The director Richard Eyre cast the two actresses after finding a "correspondence of spirit between them".[72] Winslet was drawn to the idea of playing an intellectual and zesty female lead, and in research, she read Murdoch's novels, studied her husband's memoir Elegy for Iris, and watched televised interviews of Murdoch.[73] The project was filmed over four weeks and allowed Winslet to bring her daughter, who was six months old at the time, on set.[73] Writing for The Guardian, Martin Amis remarked that "the seriousness and steadiness of [Winslet's] gaze effectively suggest the dawning amplitude of the Murdoch imagination".[74] She received her third Oscar nomination for Iris, in addition to BAFTA and Golden Globe nominations for Best Supporting Actress.[73][75] Winslet's third film release of 2001 was the animated film Christmas Carol: The Movie, based on Charles Dickens' novel. For the film's soundtrack she recorded "What If", which proved to be a commercial hit.[76][77] After a year-long absence from the screen, Winslet starred as a headstrong journalist interviewing a professor on death row in the thriller The Life of David Gale (2003). She agreed to the project to work with the director Alan Parker, whom she admired, and believed the film raised pertinent questions about capital punishment.[78] Mick LaSalle thought the film had muddled the subject and disliked both the film and Winslet's performance.[79]

Winslet at the 2006 Toronto International Film Festival

To avoid typecasting in historical dramas, Winslet actively sought roles in contemporary-set films.[80] She found it in the science fiction romance Eternal Sunshine of the Spotless Mind (2004) in which she played Clementine, a neurotic and impetuous woman who decides to erase memories of her ex-boyfriend (played by Jim Carrey).[81][82] Unlike her previous assignments, the role allowed her to display the quirky side to her personality.[83] Gondry encouraged Winslet and Carrey to improvise on set, and to keep herself agile she practised kickboxing.[82] Eternal Sunshine of the Spotless Mind proved to be a modest financial success and several critics have regarded it as one of the best films of the 21st century.[84][85] Peter Travers of Rolling Stone described it as a "uniquely funny, unpredictably tender and unapologetically twisted romance" and found Winslet to be "electrifying and bruisingly vulnerable" in it.[86] A journalist for Premiere magazine commended her for abandoning her "corseted English rose persona", and ranked it as the 81st greatest film performance of all-time.[87] Winslet considers it to be a favourite among her roles, and she received Best Actress nominations at the Oscar and BAFTA award ceremonies.[88][89][90] She has said the film marked a turning point in her career and prompted directors to offer her a wide variety of parts.[9]

Winslet was paid £6 million to star in her next release of the year, the drama Finding Neverland.[91] It is about the relationship between J. M. Barrie (played by Johnny Depp) and the Llewelyn Davies boys, which inspired Barrie to write Peter Pan; she played the boys' mother, Sylvia. Despite her reluctance to star in another period piece, Winslet agreed to the project after empathising with her character's love for the children.[80][92] Ella Taylor of LA Weekly found her to be "radiant and earthy as ever", and CNN's Paul Clinton thought she was "exceptional in a delicate and finely tuned performance".[93][94] She received a second Best Actress nomination at that year's BAFTA Award ceremony.[90] With a box office gross of $116 million, Finding Neverland became her most widely seen film since Titanic.[44][95]

In 2005, Winslet took on a guest role in an episode of the British comedy sitcom Extras, starring Ricky Gervais and Stephen Merchant. She played a satirical version of herself in it—an actress, who in an effort to win an Oscar, takes the role of a nun in a Holocaust film.[96] She received a Primetime Emmy Award for Outstanding Guest Actress in a Comedy Series nomination.[97] Within three months of giving birth to her second child, Winslet returned to work on Romance & Cigarettes, a musical romantic comedy directed by John Turturro, in which she played Tula, a promiscuous and foulmouthed woman.[98] The part required her to sing and dance, and it helped her lose weight gained during the pregnancy.[80][99] She twisted her ankle while filming one of the dance sequences.[80] Derek Elley of Variety wrote that despite her limited screen time, Winslet had "the showiest role and filthiest one-liners".[100] She turned down an offer from Woody Allen to star in Match Point (2005) to spend more time with her children.[80]

Winslet at the 60th British Academy Film Awards in 2007, where she received her fifth BAFTA Award nomination

Winslet had four film releases in 2006. She first appeared in All the King's Men, a political thriller set in 1940s Louisiana, featuring Sean Penn and Jude Law. She played the supporting part of the love interest to Law's character.[88] The film received negative reviews for its lack of political insight and narrative cohesiveness, and failed to recoup its $55 million investment.[101][102] Her next release, the drama Little Children, was better received. Based on the novel of the same name, the film tells the story of Sarah Pierce, an unhappy housewife who has an affair with a married neighbour (played by Patrick Wilson). Winslet was challenged by the role of an uncaring mother, as she did neither understand nor respect her character's actions.[103] Scenes requiring her to be hostile towards the child actress who played her daughter proved upsetting for her.[88][104] Having given birth to two children, she was nervous about the sex scenes in which she had to be nude; she took on the challenge to present a positive image for women with, in her words, "imperfect bodies".[104] A. O. Scott of The New York Times wrote that Winslet had successfully "register[ed] every flicker of Sarah's pride, self-doubt and desire, inspiring a mixture of recognition, pity and concern".[105] Once again, she received BAFTA Award and Academy Award nominations for Best Actress; the latter making her, at 31, the youngest performer to accrue five Oscar nominations.[106]

After Little Children, Winslet played a part she found more sympathetic in Nancy Meyers's romantic comedy The Holiday.[107] She played Iris, a Briton who temporarily exchanges homes with an American (played by Cameron Diaz) during the Christmas holiday season. It became her biggest commercial success in nine years, grossing over $205 million worldwide.[108] Critic Justin Chang found the film formulaic yet pleasing, and took note of Winslet's radiance and charm.[109] In her final release of the year, she voiced Rita, a scavenging sewer rat, in the animated film Flushed Away.[110] Her sole project of 2007 was as the narrator for the English version of the French children's film The Fox and the Child.[111]

Winslet had two critically acclaimed roles in 2008.[112] After reading Justin Haythe's script for Revolutionary Road, an adaptation of Richard Yates's debut novel, Winslet recommended the project to her then-husband, director Sam Mendes, and her Titanic co-star Leonardo DiCaprio.[46] The film traces the tribulations of a young married couple in 1950s suburban America. Winslet was drawn to the idea of playing a woman whose aspirations had not been met,[113] and she read The Feminine Mystique to understand the psychology of unhappy housewives from the era.[46][113] Mendes encouraged DiCaprio and Winslet to spend time together, and she believed the small set they used helped them to develop their characters' strained relationship.[46] Hailing Winslet as "the best English-speaking film actress of her generation", David Edelstein of New York magazine wrote that "there isn't a banal moment in Winslet's performance—not a gesture, not a word".[114]

Winslet at the 81st Academy Awards in 2009, where she won the Academy Award for Best Actress

To avoid a scheduling conflict with Revolutionary Road, Winslet turned down an offer to star in The Reader. After her replacement Nicole Kidman left the project due to her pregnancy, Winslet was signed to it.[115] Directed by Stephen Daldry, The Reader is based on Bernhard Schlink's novel Der Vorleser and is about Hanna Schmitz, an illiterate Nazi concentration camp guard (Winslet), who has an affair with a teenage boy. Winslet researched the Holocaust and the SS guards. To educate herself on the stigma of illiteracy, she spent time with students at the Literacy Partners, an organisation that teaches adults to read and write.[116] She was unable to sympathise with Schmitz and struggled to play the part honestly without humanising the character's actions.[112][116] Despite this, some historians criticised the film for making Schmitz an object of the audience's sympathy and accused the filmmakers of Holocaust revisionism.[117] Todd McCarthy commended Winslet for supplying "a haunting shell to this internally decimated woman", and writing for The Daily Telegraph, Sukhdev Sandhu considered her to be "absolutely fearless here, not just in her willingness to expose herself physically, but her refusal to expose her character psychologically".[118][119]

Winslet received significant awards attention for her performances in Revolutionary Road and The Reader.[120] She won a Golden Globe Award for each of these films, and for the latter, she was awarded the Academy Award and BAFTA Award for Best Actress.[112] At age 33, she surpassed her own record as the youngest performer to accrue six Oscar nominations.[112] She also became the third actress in history to win two Golden Globe Awards at the same ceremony.[121] Exhausted by the media attention during this period, Winslet took two years off work until she was ready to creatively engage again.[122]

Winslet returned to acting with the five-part HBO miniseries Mildred Pierce (2011), an adaptation of James M. Cain's novel from the director Todd Haynes. It is about the titular heroine (Winslet), a divorcée during the Great Depression struggling to establish a restaurant business while yearning for the respect of her narcissistic daughter (played by Evan Rachel Wood). Winslet, who had recently divorced Mendes, believed certain aspects of her character's life mirrored her own.[122] She was intimidated by the scope of the production, as she featured in every scene of the 280-page script.[123] She was disturbed and upset by the story, and was particularly fascinated by the complex relationship between the mother-daughter pair.[123][124] She collaborated closely with the production and costume designers, and learnt to bake pies and prepare chickens.[123] The broadcast received a limited audience but gained positive reviews.[125][126] Matt Zoller Seitz of Salon called the series a "quiet, heartbreaking masterpiece" and described Winslet's performance as "terrific—intelligent, focused and seemingly devoid of ego".[127] She received the Primetime Emmy Award for Outstanding Lead Actress, in addition to Golden Globe and SAG Award wins.[128]

The ensemble thriller Contagion from Steven Soderbergh was Winslet's first film release of 2011. She was cast as a disease detective for the CDC, and she modelled her role on Anne Schuchat, the director of the NCIRD.[129] Contagion was a commercial success, and David Denby of The New Yorker credited Winslet for capturing the essence of an exasperated woman.[130][131] Her next project was the Roman Polanski-directed Carnage, adapted from the play God of Carnage by Yasmina Reza. Set entirely inside an apartment, the black comedy follows two sets of parents feuding over their respective children. Jodie Foster, John C. Reilly, and Christoph Waltz co-starred. The cast rehearsed the script like a play for two weeks, and Winslet brought her children with her to Paris for the eight weeks of filming.[132][133] Critics found the adaptation to be less compelling than the play, but praised the performances of Winslet and Foster.[134] They both received Golden Globe nominations for it.[135]

Winslet attending the premiere of Labor Day at the 2013 Toronto International Film Festival

Winslet said her workload in 2011 helped her overcome heartbreak from her divorce, and after completing work on Carnage she took a break from acting to focus on her children.[7][122] A short part that she had filmed four years prior for the anthology film Movie 43 was her sole screen appearance of 2012, and it yielded the worst reviews of her career.[136][137] Winslet also performed an audiobook recording of Émile Zola's novel Thérèse Raquin.[138][139] She was reluctant to accept Jason Reitman's offer to star in his 2013 film adaptation of Joyce Maynard's novel Labor Day, but agreed after Reitman postponed the production for a year to accommodate Winslet's commitment to her children.[7] Set over a Labor Day weekend, it tells the story of Adele (Winslet), an agoraphobic single mother, who falls in love with an escaped convict. Describing Adele's characterisation as having "more vulnerability than strength", Winslet found her a departure from the strong-willed women she typically played.[7] A scene in the film required her to make a pie, for which she drew on her baking experience from Mildred Pierce.[140] Reviews of the film were negative; Chris Nashawaty of Entertainment Weekly dismissed it as "mawkish and melodramatic" but credited Winslet for adding layers to her passive role.[141][142] She received her tenth Golden Globe nomination.[143]

The novelty of playing a villain drew Winslet to the part of Jeanine Matthews in the science fiction film Divergent (2014).[144][145] Set in a dystopian future, the adaptation of Veronica Roth's young adult novel stars Shailene Woodley as a heroine fighting an oppressive regime headed by Winslet's character. She was pregnant with her third child during production, and her tight-fitting costumes had to be altered to accommodate the pregnancy.[145] To maintain her character's intimidating persona, she remained aloof from her co-stars for much of the filming.[144] Richard Lawson of Vanity Fair compared the film unfavourably to the Hunger Games series, and found Winslet to be underutilised in it.[146] The film grossed $288 million worldwide.[147] A Little Chaos marked her return to the period film genre.[148] Directed by Alan Rickman, it is about a rivalry among gardeners commissioned to create a fountain at the Palace of Versailles. Winslet's role was that of fictional architect Sabine de Barra, a character she believed had overcome extreme grief and hardship like herself.[148] Catherine Shoard of The Guardian took note of the "emotional honesty" Winslet brought to her part, but criticised the implausibility of her role.[149] Also that year, she read audiobooks of Roald Dahl's children's novels Matilda and The Magic Finger.[150][151]

Winslet at the premiere of Divergent in 2014

In 2015, Winslet reprised the role of Jeanine Matthews in the second instalment of the Divergent series, subtitled Insurgent, which despite negative reviews grossed $297 million worldwide.[152][153] Her next film, an adaptation of the Australian gothic novel The Dressmaker, was described by the director Jocelyn Moorhouse as being reminiscent of the western Unforgiven (1992).[154] Winslet starred as the femme fatale Tilly Dunnage, a seamstress who returns to her hometown years after she was accused of murder. She learnt to sew for the part and designed some of her own costumes.[154] The project was filmed in the Australian desert and she found it difficult to wear couture dresses in the harsh weather.[155] Despite disliking the film, Robert Abele of the Los Angeles Times credited Winslet for underplaying her over-the-top part.[156] The film emerged as one of the highest-grossing Australian films of all time, but earned little elsewhere.[157][158] Winslet won the AACTA Award for Best Actress.[159]

While filming The Dressmaker, Winslet became aware of a forthcoming Steve Jobs biopic written by Aaron Sorkin and directed by Danny Boyle. Keen on playing Jobs's marketing chief and confidante Joanna Hoffman, she sent a picture of herself dressed as Hoffman to the film's producer.[160] Steve Jobs, starring Michael Fassbender in the title role, is told in three acts, each depicting a key milestone in Jobs's career. In preparation, Winslet spent time with Hoffman, and worked with a dialect coach to speak in Hoffman's accent, a mixture of Armenian and Polish, which she considered to be the most difficult of her career.[160] The cast rehearsed each act like a play and filmed it in sequence. Winslet collaborated closely with Fassbender, and their off-screen relationship mirrored the collegial dynamic between Jobs and Hoffman.[160] The film earned her some of the best reviews of her career, though it was a box-office flop.[45][161][162] Peter Howell of the Toronto Star commended Winslet for finding "strength and grace" in her part, and Gregory Ellwood of HitFix thought she had improved on Hoffman's characterisation.[163][164] She won the Golden Globe and BAFTA Awards for Best Supporting Actress, and received her seventh Oscar nomination.[165]

Winslet attending an event for The Mountain Between Us at the 2017 Toronto International Film Festival

John Hillcoat's ensemble crime-thriller Triple 9 (2016) featured Winslet as Irina Vlaslov, a ruthless Russian-Israeli gangster.[166] The critic Ann Hornaday of The Washington Post felt Winslet had failed to effectively portray her.[167] Her next release of the year, Collateral Beauty, about a man (played by Will Smith) struggling with the death of his daughter, was panned by critics.[168] Writing for New York magazine, Emily Yoshida dismissed the film as a vacuous remake of A Christmas Carol and added that Winslet had "never looked more painted and tired".[169] It was a modest earner at the box office.[170] Winslet agreed to the romantic disaster film The Mountain Between Us (2017) to take on the challenge of a role requiring physical exertion.[171][172] It featured Idris Elba and her as two strangers who crash land on an icy and isolated mountain range. They filmed in the mountains of Western Canada at 10,000 feet (3,000 metres) above sea level where the temperature was well below freezing.[172] Winslet performed her own stunts and described it as the most physically gruelling experience of her career.[173] Moira Macdonald of The Seattle Times opined that the duo's charisma and chemistry had enhanced a mediocre film.[174]

Woody Allen's Wonder Wheel, a drama set in 1950s Coney Island, was Winslet's final release of 2017. She played Ginny, a temperamental housewife having an affair with a lifeguard (played by Justin Timberlake). She described her character as permanently dissatisfied and uneasy; playing the part proved difficult for Winslet, who suffered from anxiety.[172][175] Manohla Dargis of The New York Times disliked Allen's writing but credited Winslet for filling her "shabby character with feverish life".[176] When asked during the film's promotion about her decision to work with Allen despite an allegation of child molestation against him, Winslet chose not to comment on the filmmaker's personal life but stated she was pleased with the collaboration.[172] She would later go on to express regret over working with both Allen and Roman Polanski.[177] In 2019, Winslet provided her voice to Moominvalley, an animated television series about the Moomins, and took on a leading role alongside Susan Sarandon and Mia Wasikowska in Blackbird, a remake of the Danish film Silent Heart (2014).[178] Benjamin Lee of The Guardian dismissed it as "less of a film and more of an actors' workshop" and found Winslet miscast.[179]

Winslet portrayed palaeontologist Mary Anning in Ammonite (2020), a period drama about a romance between Anning and Charlotte Murchison (played by Saoirse Ronan) set in 1840s England.[180] She dropped out of Wes Anderson's The French Dispatch to have more preparation time for the project. She collaborated closely with Ronan, and they choreographed their own sex scenes.[181] For much of the filming, she lived in isolation in a rented cottage in Dorset, where the film was shot, to get into her character's headspace.[177] Caryn James of the BBC credited Winslet for portraying Anning as "stern and brittle but immensely sympathetic" and considered her "contained, potent performance" to be one of the best of her career, and Manuel Betancourt of New York magazine welcomed it as a "return to form".[182][183] She next voiced the titular horse in a film adaptation of the novel Black Beauty.[184]

The following year, Winslet executive produced and starred in Mare of Easttown (2021), an HBO miniseries about a troubled police detective solving a murder case.[185] Set in Delaware County, Winslet insisted on using the "Delco accent", a version of Philadelphia English used in the county; she considered it to be the one of the hardest accents she has had to learn.[186][187] The series and Winslet's performance received critical acclaim;[188] Richard Roeper wrote that she "adds to a long list of magnificent, disappear-into-the-character performances" and Lucy Mangan of The Guardian opined, "If you can have a defining performance this late in a career, this is surely Winslet's. She is absolutely wonderful."[189][190] Mare of Easttown proved to be a ratings hit for HBO,[191] and Winslet once again won the Primetime Emmy Award, Golden Globe, and SAG Awards for Best Actress in a miniseries.[192] The following year, she narrated the documentary Eleven Days in May, about the 2021 bombing of Gaza by Israel.[193]

Following Mare of Easttown, Winslet took a year off work to spend time with her family.[194] Avatar: The Way of Water, a science fiction sequel to James Cameron's 2009 film, which she had filmed using motion capture technology in 2017 and 2018, will release in 2022.[175][195] She learnt freediving for her role and was able to hold her breath underwater for seven minutes.[196] Winslet will next portray the model and war photographer Lee Miller in the biopic Lee.[197] Production in Croatia was suspended for a short period when Winslet slipped while filming.[198] She will star with her daughter Mia Threapleton in an episode of the Channel 4 anthology series I Am..., titled "I Am Ruth".[199] Winslet will also collaborate with HBO on two more limited series: Trust, based on Hernan Diaz's novel,[200] and The Palace, directed by Stephen Frears, which she will also executive produce.[201]
