Taxi Driver is a 1976 American psychological thriller film directed by Martin Scorsese, written by Paul Schrader, and starring Robert De Niro, Jodie Foster, Cybill Shepherd, Harvey Keitel, Peter Boyle, Leonard Harris, and Albert Brooks. Set in a decaying and morally bankrupt New York City following the Vietnam War, the film tells the story of Travis Bickle, a lonely taxi driver who descends into insanity as he plots to assassinate both the presidential candidate for whom the woman he is infatuated with works, and the pimp of an underage prostitute he befriends.
Travis Bickle is a lonely, depressed 26-year-old honorably discharged U.S. Marine and Vietnam War veteran living in isolation in New York City. Travis takes a job as a night shift taxi driver to cope with his chronic insomnia, driving passengers around the city's boroughs. He frequents the porn theaters on 42nd Street and keeps a diary in which he consciously attempts to include aphorisms, such as "you're only as healthy as you feel."
