Looper Teaser of the Day

Rian Johnson's time-traveling hitman flick Looper gets in on the trailer-for-the-trailer trend with a teaser video featuring Johnson and Joseph Gordon-Levitt. The teaser gives us the first actual footage from Looper, as well the most concise explanation of the movie's premise yet -- "What would you do if you had to hunt down and kill your future self?" The full-on JGL vs. Bruce Willis trailer is due out on Thursday, and Looper opens September 28th. [
