Bruce Willis, Joseph Gordon-Levitt face off in 'Looper' clip -- VIDEO

In anticipation of its premiere at the Toronto Film Festival next week, the first clip from the sci-fi thriller Looper hit the Web today, featuring Joseph Gordon-Levitt and Bruce Willis as the same man, 30 years apart. The younger man (Gordon-Levitt) is one of the titular Loopers, a class of mob assassin tasked with offing marks zapped from the future — until their loop is “closed” when they have to kill their future self (in this case, Willis).

Confused? Don’t sweat it too much. As Willis himself makes clear in this clip, trying to figure out the metaphysics of time travel is an exercise in futility. Much more important, to the characters and to the film: What would happen if you had to face down your future self?
