James Bond hunk Daniel Craig stars in 'Defiance' and ET was on the red carpet for the film's AFI Fest premiere Sunday night to get the behind-the-scenes details from his co-stars Liev Schreiber and Jamie Bell!

Liev tells ET that despite the film's serious subject matter, the cast had a great time working together. "We had a lot of fun, which was important because what we were doing was really quite somber." He goes on to reveal that co-star Craig has a playful side most people aren't aware of: "Daniel Craig is far more entertaining and just downright goofy than I think most people think he is, and that's a result of that Bond thing he's doing"

Based on the book Defiance: The Bielski Partisans by Nechama TecCast, the film finds the trio as Jewish brothers who band together for survival but end up avenging the deaths of their loved ones and saving countless others during World War II.
