At this year's Comic-Con, an extended red band trailer of Legion screened and it was pretty incredible. Now it's here, and it's one of the craziest trailers you'll see this month. Paul Bettany stars as the angel Michael, sent to earth to protect an unborn child who's the last hope of humanity. There are so many movies coming out that are post-apocalyptic, but here's one with the balls to show us the actual apocalypse itself. Prepare yourself for over five minutes of terrifying action. You deserve it. Check it out after the jump.
