You may watch below the official movie trailer of Looper, the upcoming science-fiction thriller directed by Rian Johnson:
Hard to believe that the mob could get their hands on a sensitive technology like time travel. And sending people back in time just to have them killed doesn't sound efficient (I mean why don't they just kill them in their time?). But well, judging from the trailer it's still going to be a quite entertaining movie. So I guess I'll go watch Looper.
