First full trailer for Rian Johnson's sci-fi action flick Looper, which stars Joseph Gordon-Levitt as an assassin assigned to kill his future self, played by Bruce Willis.
The trailer is wall-to-wall action, but it leaves a few things up in the air, like why JGL's clients want him dead, what happens when a looper's victim escapes, and how time travel will affect Bruce Willis's brain.
Looper, also starring Paul Dano, Noah Segan and Emily Blunt, is due out September 28.
