Nicholson to play Irish gang boss

Jack Nicholson is joining Matt Damon and Leonardo DiCaprio in their upcoming movie The Departed - as an Irish gang boss.

Nicholson has met longtime pals DiCaprio and director Martin Scorcese about the movie, a remake of the Chinese film Internal Affairs, featuring Damon and DiCaprio as opposing undercover cops.

He says: "(I've been) looking for a bad guy - I just did three comedies. (DiCaprio, Scorsese and I) had been looking for something to do together."

Of his Boston Irishman role, he jokingly adds: "I won't have to act much."

Mark Wahlberg will also appear in the movie, which has yet to cast a female psychiatrist.
