The full Looper trailer is finally here. And Rian Johnson's sci-fi flick looks positively loopy. In the best way possible.

"Time travel has not yet been invented. But 30 years from now, it will have been," begins a scratchy-voiced Joseph Gordon Levitt. It's reassuring to know that someone's keeping track of all the tenses flying around. 

An assassin paid to take people from the future and kill them in the past, everything's going swimmingly for the young Looper. Until he finds out someone has been paid to do the same thing to him: himself (Bruce Willis).

Follow all that? Not really. Excited about it? Hell yes.

Read on to watch the full Looper trailer - or see it in HD at Apple. And if anyone mentions a teaser for a teaser for a trailer to me again, I'll travel back in time myself and shoot them in the balls.
