Ben Affleck and Matt Damon are combining their star power once again. Studio Warner Bros. Pictures tells CNN that Affleck is set to direct as well as co-star along with Matt Damon in a film about infamous gangster Whitey Bulger. The yet-to-be-titled film will be produced by the Boston filmmakers as well, under their production company Pearl Street Films. Damon is signed on to portray Bulger, who was just recently apprehended after more than 16 years on the run. "Sopranos" and "Boardwalk Empire" scribe Terence Winter is taking care of the screenplay, which will chronicle Bulger's journey from his "misspent youth" to becoming one of the most notorious criminals in history. The studio didn't clarify what role Affleck will take on, but Deadline reports his brother Casey will also join the cast in a supporting role. According to the site, Affleck says that he and co-star Damon "have been looking for something to do together for some time. We've heard about Whitey Bulger since we were kids, and we are excited about the prospect of putting it on screen."
