Robert DeNiro

Robert DeNiro was originally offered the role of Frank Costello in Martin Scorsese's “The Departed” but he turned it down, and so the part was given to Jack Nicholson. Also, Ray Liotta was offered the part of Dignam, but he had to pull out due to scheduling conflicts, and so the part went to Mark Walhberg. Brad Pitt, whose production company Plan B made the movie, was set to play Colin but dropped out to work on another movie, so Matt Damon was brought in as his replacement. The 2006 film boasted an enviable cast of A-list actors many filmmakers would shamelessly campaign to work with. As a result fifty percent of the film's budget was spent on the actors' salaries.
