Here we have some behind-the-scenes footage from Lynne Ramsay's We Need To Talk About Kevin, a film exploring the emotional fallout from a teenager's violent act—and the relationship with his mother that predates it. It's a fascinating, troubling, somewhat divisive movie, though nobody seemed divided on the idea that Tilda Swinton is excellent in it. In this exclusive clip, you'll hear from Ramsay (whose awesome track record also includes Ratcatcher and Morvern Callar) as well as Swinton and teen lead Ezra Miller. The DVD comes out today, and you can enter our contest here to win it, as well as some other cool stuff. (Can you say "cool" about a movie and book that deals with high-school violence?)
