The Departed

Originally, Jack Nicholson turned down his role in the movie, but after a meeting withMartin Scorsese, William Monahan and Leonardo DiCaprio, he was finally convinced to play the role of Frank Costello. The main reason he joined the production was because he had previously done a few comedies, and wanted to play a villain again, and he considered the character of Costello to be the ultimate incarnation of evil.
