Gaspar Noé's "Irreversible" is a prime example of an irreversible film. The movie tells the story of Mark (played by Vincent Cassel), a young man who seeks revenge against the men who brutally raped and left his girlfriend, Alex (played by Monica Bellucci), for dead. The film is known for its graphic and disturbing portrayal of the rape scene, which lasts for approximately 12 minutes and is shot in a single, unbroken take.
