Mark Wahlberg recalls Jack Nicholson shutting down his improvisation while filming Martin Scorsese’s The Departed. Released in 2006, The Departed stars Leonardo DiCaprio as Billy, an undercover cop attempting to infiltrate Costello’s (Nicholson) criminal organization while uncovering a mole in the police department. The crime thriller features a standout cast, including Matt Damon, Alec Baldwin, and Martin Sheen, with Wahlberg playing Dignam, a prickly sergeant in the Massachusetts State Police.
