Domino Vitali

Born Dominetta Petacchi, she is an Italian beauty from Bolzano who went to school in England at Cheltenham Ladies' College. She later studied acting at the Royal Academy of Dramatic Art until being forced (after her parents' death in a train wreck) to return to Italy, where she became an actress. She changed her surname to Vitali, a stage name. While in Italy she also became the mistress of Emilio Largo, whom she calls a "guardian" of no relation.

Bond meets Domino while in Nassau. She is staying on Largo's yacht, the Disco Volante, and believes Largo is in the area on a treasure hunt. For reasons she does not understand Largo makes her stay on land while he and his partners (whom she describes as shareholders) go prospecting for the hidden treasure. She also tells Bond that she has never been able to see the map that they use. Although Bond is successful in engaging Domino in conversation, she snubs him, but later agrees to meet with him again when she returns to land. She also becomes testy when Bond uses her given name, Dominetta, and bluntly tells him to call her 'Domino'.

When Bond and Domino meet again at the casino later, she has entirely changed. She tells Bond that she is tired of watching Largo show off and letting him use her. She explains to Bond that she is trapped like a bird in a gilded cage. Domino later reveals that Giuseppe Petacchi is her brother whom she has not seen for some time. Bond finds out that Largo had Petacchi killed after Petacchi had hijacked a bomber on SPECTRE's behalf. He proves this to Domino, and recruits her as an ally to spy on Largo. Domino returns to Largo's yacht, the Disco Volante, with a geiger counter to verify the ship as the location of the two stolen nuclear bombs, however, she is uncovered and taken prisoner. Largo tortures her by burning her with a cigar for heat and then using ice cubes for cold.

Domino ultimately escapes as Largo attempts to carry out his plan. Before he can kill a weakened James Bond, she appears behind him and shoots him through the neck with a harpoon from a spear gun, avenging her brother.

In early drafts of the film's screenplay, the character's name was Dominetta Palazzi. When Claudine Auger was cast as Domino, the character's surname was changed to Derval to reflect her nationality.

Dominique Derval is seen when Bond is swimming in Nassau, her foot gets stuck in coral on the ocean floor but Bond sets her free. She swims up to her boat and thanks Bond. Bond swims back to his boat with his Nassau contact, Paula Caplan. Paula takes care of their boat, as Bond is about to learn more about Domino. Domino and Bond have lunch on the beach, but Quist spies on the two, a sign that Domino had to go back to the yacht Disco Volante. At the hotel Bond stayed in, Bond sees Domino with Largo, Domino smoking a cigar, as Bond bids in the game against Largo. Domino tells Largo that Bond has pressed her to a drink. Domino and Bond slow-dance outside but Largo collects her.

Upon arriving at Largo's home in Palmyra, Domino is swimming when Bond visits. After leaving to make lunch, Largo invites Bond to the Nassau Junkanoo. Domino accompanies them and informs Bond that Felix Leiter is trying to contact him. Bond then searches for Paula, who had been kidnapped by Fiona Volpe. He finds out that Paula committed suicide with cyanide. The next day, Domino and Bond make love in the water. They go on shore and Bond tells Domino the story: Largo killed her brother, a French Air Force pilot assigned to NATO, in order for SPECTRE to steal a Royal Air Force Avro Vulcan strategic bomber with two nuclear bombs. Largo, as a senior SPECTRE operative, plans to create a nuclear holocaust using the weapons.

Domino then aids Bond by helping him kill Vargas and spying on the Disco Volante, but Largo captures and tortures her. Domino escapes and kills Largo with a harpoon in the back. She and Bond then jump off Volante just in time before it explodes. They are immediately rescued by the CIA B-17 and carried into the air on a sky hook.

Domino Petachi (played by Kim Basinger) is structured after Domino Derval. The character is called Domino, it is no longer just a nickname, but her last name has changed to Petachi, similar to the novel's original Petacchi. Unlike in the first film version where she refers to Largo as her "guardian," there is no disguising the fact they are involved romantically.

She meets Bond at a spa in Monte Carlo, where he poses as a masseur and massages her for information. This gives her immense pleasure, though she later realizes he is not who he appears to be. She encounters him again at a casino where Bond introduces himself to her. They have drinks before being interrupted by Largo. The two dance briefly, where Bond informs her about the death of her brother Jack. Bond is then invited to Largo's yacht, where Largo spies on them kissing in her cabin. He leaves Bond manacled near Palmyra, while Domino is auctioned off as a slave to some unsavory Arabs. Bond eventually escapes and rescues her. They are then chased by the Arabs on horseback until the horse jumps off a cliff into the ocean. They are rescued from the water by Felix Leiter and a team from MI6. After their rescue, Domino and Bond track Largo to a location known as "The Tears of Allah". The two take a shower together, and Bond kisses her before heading off to stop Largo. The circumstances of her spearing Largo as he and Bond fight are altered from the original film – here it takes place underwater, with all the characters in scuba gear. The film ends with Bond indicating his intention to retire from MI6 and settle down with Domino.
