Hilary Duff, pictured in 2009, serves as the program's central focus during its two-season run.

In 2000, Hilary Duff was asked to audition for a series on Disney Channel.[2] Created by Terri Minsky, the series was known by the working title What's Lizzie Thinking? throughout development.[2][3][4] The series was later retitled Lizzie McGuire, and Duff successfully auditioned for the title character of Lizzie, who was described as a regular teenager.[2][3] The premise for the series was based on a script previously written by Minsky, which featured the main character's inner thoughts and emotions as narration.[5] Producer Stan Rogow conceived a high-concept version of the script in which an animated version of the character would be featured to convey these thoughts. This concept became known the "animated Lizzie" persona, and was also voiced by Duff.[5] The animation was originally envisioned as a talking head in the corner of the screen.[6] Rogow stated that the visual design of the show was inspired by the film Run Lola Run.[5]

Independent animator Debra Solomon designed the animated version of Lizzie, based on Duff's appearance on her audition tape.[6] Rather than drawing a mere caricature of Duff, she tried to capture the actress's essence by giving Lizzie's alter ego a more "hip" look: cropped shirts with trim pants and high flip-flops.[6] New York's Tapehouse Toons produced the animation along with Kratky Studios.[7] The drawings were digitally inked and painted using the Animo 3.1 software and then composited into the live-action footage at Disney's Los Angeles studio.[7] Due to the low budget given by Disney, there are only two minutes of animated Lizzie in each episode.[6]

In July 2001, a second season of 22 episodes were ordered, to begin production in September and air in 2002.[8] Lalaine's character Miranda did not appear in the last 5 episodes filmed for the second season, or The Lizzie McGuire Movie, due to Lalaine leaving the series early to work on other projects such as You Wish!.[9] Filming of the movie and series concluded in December 2002 after 65 episodes were produced, a standard limit for Disney Channel's series.[10][11]

In May 2003, it was revealed that Lizzie McGuire would end production due to contract disagreements between Duff and Disney.[10][12] The company was interested in transitioning the program into a high school-centered series for ABC and expanding the franchise with a further film, while Duff was receiving offers for lucrative roles with other studios.[10][12] After the series ended its original run, Disney Channel also considered producing an animated version of the series.[10] In November 2004, a pilot for an intended spin-off was ordered, which was to center on Miranda's younger sister Stevie Sanchez and her Latino family.[11] The series would follow the 12-year-old central character, who was played in the pilot by Selena Gomez, and would also feature an animated version of the character like Lizzie.[11] It was to star LaLaine, and be produced by Minsky and Rogow.[11] The pilot was produced in 2005, but the series was not picked up in favor of Hannah Montana.[11][13]

In 2014, Duff stated that she would be open for a reunion, and in December 2018, stated that there had been discussions about reviving the series.[14][15] On August 23, 2019, it was officially announced at the D23 Expo that Disney was developing a revival television series of Lizzie McGuire.[16][17][18] The series was revealed to be in production for exclusive distribution on the Disney+ streaming service, with Duff reprising her role as the title character; the original series creator, Terri Minsky, planned to serve as the reboot's showrunner.[16][17][18] The sequel series would have centered on Lizzie at the age of thirty, navigating life working as an apprentice to an interior decorator. She would be living in an apartment in Brooklyn, New York City, engaged to a man who owns a restaurant in SoHo, Manhattan.[16][17][19] When Lizzie discovers her fiancé cheating on her, she returns home to Los Angeles.[20][21] It was revealed that the animated alter ego of Lizzie would also have appeared in the series.[17] The series was to be produced by Salty Pictures in association with Disney Channel as part of an overall deal with Minsky.[16][19] Duff was to serve as an executive producer, alongside Rachel Winter, and co-executive producer Ranada Shepard.[19] In October 2019, it was announced that Thomas, Todd and Carradine would also return to the series, reprising their roles as Matt, Jo and Sam McGuire respectively.[22] Production on the sequel series began on October 29, 2019, on location in Washington Square Park in New York.[23] Further filming for the series would have taken place in Los Angeles.[24] In November, it was revealed that Federico Dordei would be joining the cast as new character, Dominic Shaw, and that Lamberg would be reprising his role as Gordo.[19][24]

Minsky departed as the showrunner of the revival in January 2020 after the first two episodes of the series had been filmed, due to creative differences with Disney.[25][26] Production of the series was placed on a hiatus and delayed until a new showrunner would be decided, with speculation that Minsky had been fired and the series would be canceled.[25][27] In February 2020, Duff hinted on social media that production had stopped because the series was not thought "family-friendly" enough by Disney+ executives.[27] Disney reaffirmed that the development of the series was ongoing and that a new showrunner had not yet been decided.[27] Duff later posted a statement publicly pleading for Disney+ to move the series to Hulu as had been done with Love, Victor and High Fidelity, stating that it would allow the series to fully represent the life of a thirty-year-old without the constraints of a "family friendly" classification.[28] The Hollywood Reporter stated that the first episode's script featured references to sex and involved cheating as a central plot point.[29][21] It was reported in April that Minsky was in contact with the writers of the series, and Duff was still in talks with Disney;[30] however, in December 2020, Duff announced that the revival was officially canceled.[31][32][33]

Walt Disney Pictures released a film based on the series, The Lizzie McGuire Movie, on May 2, 2003, in the United States.[38] Set after the conclusion of the series and her junior high graduation, the film follows Lizzie and her classmates on a school trip to Rome, Italy.[39] It earned $42.7 million at the U.S. box office and $12.8 million internationally, for a total of $55.6 million worldwide.[18][40] The film received mixed reviews from critics, who found it superficial, but thought the show's fans would enjoy it.[41]

Throughout the early 2000s, the series' popularity led Disney to release merchandise, including a series of books and comics, a Lizzie McGuire character doll, a bedroom set, and board games. Disney Interactive published three video games for the Game Boy Advance, including: Lizzie McGuire: On the Go! in 2003, Lizzie McGuire 2: Lizzie Diaries in 2004, and Lizzie McGuire 3: Homecoming Havoc in 2005.[42][43][44] Toys were also released through a partnership with McDonald's in 2004. Fortune estimated in 2003 that Lizzie McGuire merchandise had earned nearly $100 million.[45] Two soundtracks for the series were produced, Lizzie McGuire and Lizzie McGuire Total Party![46][47]
