The Departed is a 2006 American crime thriller film directed by Martin Scorsese. The screenplay by William Monahan was based on the 2002 Hong Kong film Infernal Affairs. The film stars Leonardo DiCaprio, Matt Damon, Jack Nicholson, and Mark Wahlberg, with Martin Sheen, Ray Winstone, Vera Farmiga, Anthony Anderson, and Alec Baldwin in supporting roles. It won several awards, including four Oscars at the 79th Academy Awards: Best Picture, Best Director (Scorsese), Best Adapted Screenplay and Best Film Editing. Wahlberg was nominated for Best Supporting Actor. The film takes place in Boston, where Irish Mob boss Francis 'Frank' Costello (based loosely on Whitey Bulger) plants Colin Sullivan as an informant within the Massachusetts State Police. Simultaneously, the police assign undercover cop William 'Billy' Costigan to infiltrate Costello's crew. When both sides realize the situation, each man attempts to discover the other's true identity before his own cover is blown.
