The concept here is that there's a future where time travel exists, but is highly illegal and only utilized by serious criminals, mostly as a means of murder without evidence.  See, a victim-to-be is sent back in time thirty years, where a looper offs him or her then gets rid of the body.  When a young looper's latest execution is himself, though, things get complicated pretty quickly.  Action ensues.

Johnson, whose record as writer-director is so spotless it shines after the marvelous Brick and the whimsical The Brothers Bloom, took to Twitter (@rcjohnso) to caution, "If you're already set on seeing Looper, I'd avoid any trailers from here on out. They don't ruin the movie, but they tip a few little things that are fun to discover in the context of the movie."

He added that they're not "particularly spoilery," but that it's just in the nature of trailers.  You've been warned.

Hot damn.  Thanks to MSN UK for hosting the trailer's debut today.

Everything we've seen from Looper promises something special, which is cheese on a hot dog (see: icing on cake) since this movie had me at "Rian Johnson making a science fiction film."  The way Gordon-Levitt is channeling Willis without parroting him is really interesting, especially since we've known Willis as an actor for thirty years, but the younger actor isn't doing the comedic Willis of decades past.  Instead he's got the actor's serious persona down pat.

Anyways, the trailer hints that Garret Dillahunt has a more significant role than we previously thought, and that's welcome news since Dillahunt never fails to create compelling characters even with minimal screentime.  Other members of the supporting cast include Emily Blunt, Jeff Daniels, Paul Dano, Piper Perabo, and Noah Segan, who Brick fans remember well as the unfortunate Dode.

Looper arrives in theaters on September 28th.  Check back tomorrow for the new domestic trailer.
