Sharing an instant attraction, Nick and Alice make out in the ladies' room and set a lunch date for Friday. The following morning, a hungover Nick attends a shareholders' meeting at Magnascopic Laboratories. Unable to endure the droning presentation by Dr. Bernard Wachs (Jim Norton), Nick leaves the room for a nap. A lab technician (Aaron Lustig) accidentally spills his mug of coffee onto a computer console, causing a meltdown, and the entire building is evacuated. The building seems to explode, but there is no debris. Instead, much of the building is rendered invisible, including Nick. Shady CIA operative David Jenkins (Sam Neill) arrives on the scene, and discovers Nick's condition. While they are transferring him to an ambulance, the agents joke about how Nick will spend the rest of his life being studied by scientists. In a panic, Nick flees.

Generate a question that has the following answer: Italian for the following movie plot: As the film opens, Joe Buck (Jon Voight), a young Texan working as a dishwasher, dresses in new cowboy clothing, packs a suitcase, and quits his job. He heads to New York City hoping to succeed as a male prostitute for women. Initially unsuccessful, he succeeds in bedding a well-to-do middle-aged New Yorker (Sylvia Miles), but Joe ends up giving her money. Joe then meets Enrico Salvatore "Ratso" Rizzo (Dustin Hoffman), a street con man with a limp who takes $20 from Joe by offering to introduce him to a known pimp (John McGiver). Joe flees the encounter in pursuit of Ratso. Joe spends his days wandering the city and sitting in his hotel room. Soon broke, he is locked out of his hotel room and most of his belongings are impounded. He tries to make money by agreeing to receive oral sex from a young man (Bob Balaban) in a movie theater. When Joe learns that the young man has no money, Joe threatens him and asks for his watch, but eventually lets him go. The following day, Joe spots Ratso and angrily shakes him down. Ratso offers to share the apartment in which he is squatting in a condemned building. Joe accepts reluctantly, and they begin a "business relationship" as hustlers.

He dreams of moving one day to Miami. An unusual couple approach Joe and Ratso in a diner and hand Joe a flyer, inviting him to a party.

Problem: Given the question: Generate a question that has the following answer: Barts for the following movie plot: In 1818, Abraham Lincoln (Benjamin Walker) lives in Indiana with his parents, Nancy (Robin McLeavy) and Thomas (Joseph Mawle), who works at a plantation owned by Jack Barts (Marton Csokas). There, Lincoln befriends a young African American boy, William Johnson (Anthony Mackie), and intervenes when he sees Johnson being beaten by a slaver. Because of his son's actions, Thomas is fired. That night, Lincoln sees Barts break into his house and attack Nancy. She falls ill the following day, and dies shortly afterwards. Thomas tells Lincoln that Barts poisoned Nancy. Nine years later, Lincoln decides to get revenge against Barts. He attacks Barts at the docks, but Barts, who is actually a vampire, overpowers him. However, before Barts can kill him, Lincoln is rescued by Henry Sturgess (Dominic Cooper). Sturgess explains that vampires exist, and offers to teach Lincoln to be a vampire hunter. Lincoln accepts and, after a decade of training, travels to Springfield, Illinois. During his training, Sturgess tells Lincoln that the vampires in America descend from Adam (Rufus Sewell), a vampire who owns a plantation in New Orleans with his sister, Vadoma (Erin Wasson). Sturgess also tells Lincoln of the vampires' weakness, silver, and presents him with a silver pocket watch. In Springfield, Lincoln befriends shopkeeper Joshua Speed (Jimmi Simpson), and meets Mary Todd (Mary Elizabeth Winstead). Though Sturgess warned him not to form any close relationships, Lincoln develops romantic feelings for Mary. Lincoln successfully finds and defeats Barts. Before dying, Barts reveals that Sturgess is also a vampire. Lincoln confronts Sturgess, who reveals that, several years ago, he was attacked and bitten by Adam. Because Sturgess' soul was impure, he became a vampire, and that prevented him from harming Adam or any other vampire (since "Only the living can kill the dead"). Sturgess has since been training vampire hunters, hoping to destroy Adam. Disappointed, Lincoln decides to abandon his mission. However, Adam learns of his...
