By far the best trailer for Brad Pitt's new movie Fury, coming out in October. This one showcases newbie Logan Lerman and gives us much more of the actual story, set amidst the tank warfare during WWII. The studio chose not to premiere this at any of the film festivals, which I'm not sure is a good sign or not- it could be that they think it's more of a commercial than awards play, but considering the subject matter (anything WWII-related is Oscar catnip) they might have at least made a try for it.
