With writer-director Rian Johnson's Looper opening September 28, Sony has provided us with four clips from the fantastic film.  The film takes place in a future where time travel exists, but it’s only used on the black market.  Joseph Gordon-Levitt plays a “Looper”, a hitman who is contracted to kill people that are sent back in time, and then disposes of the bodies so the victim technically no longer exists.  Things go awry when his future self (Bruce Willis) is sent back in time as an assignment and then escapes.  The film also stars Emily Blunt, Jeff Daniels, and Paul Dano.For more on the film, here's Matt's review and all our previous coverage.  Hit the jump to watch the clips.Here's the synopsis for Looper:

 In the futuristic action thriller Looper, time travel will be invented – but it will be illegal and only available on the black market. When the mob wants to get rid of someone, they will send their target 30 years into the past, where a “looper” – a hired gun, like Joe (Joseph Gordon-Levitt) – is waiting to mop up. Joe is getting rich and life is good… until the day the mob decides to “close the loop,” sending back Joe’s future self (Bruce Willis) for assassination. The film is written and directed by Rian Johnson and also stars Emily Blunt, Paul Dano, and Jeff Daniels. Ram Bergman and James D. Stern produce.
