Looper

Release Date: September 28

The Plot: Joseph Gordon-Levitt is a time-traveling hit man tasked with taking out the older version of himself -- played by Bruce Willis -- in this futuristic thriller. In the Looper world, time travel is illegal and only available on the black market. When the mob wants to get rid of someone, they send their target 30 years into the past, where a "looper" -- a hired gun, like Joe (Gordon-Levitt) -- is waiting to mop up. Joe lives the good life with his job as a looper – until one day the mob decides to "close the loop," sending back Joe's future self (Willis) for assassination. Will he kill himself, or team up to get revenge? Written and directed by Rian Johnson, Looper also stars Emily Blunt, Paul Dano and Jeff Daniels.

Why It's a Must-See: Joseph Gordon-Levitt's "It" factor continues to rise after pivotal roles in Inception and The Dark Knight Rises, and Looper looks to be a clever, thinking person's sci-fi actioner. "It's more Chris Nolan than Michael Bay," Joe tells ET. "If you like a fun time and a bangin'-ass movie, you'll get that. If you also like a more grown-up drama, you'll also get that. It's one of those movies."
