Dylan O'Brien Is Bearded and Shirtless in the American Assassin Trailer

In between shooting the Maze Runner films and the final season of Teen Wolf, Dylan O'Brien managed to sneak in an action film named American Assassin . . . and I am truly taken aback by the trailer. Our baby-faced Stiles is gone, and in his place is this scruffy, weapons-savvy mini Jason Bourne. He's playing an assassin-in-training, mentored by none other than Michael Keaton. Sanaa Lathan and Taylor Kitsch (don't blink or you'll miss him in the trailer) are in supporting roles, but it's really all about O'Brien here. The movie is out Sept. 15 and the song in the trailer is "The Answer" by Unkle.
