Looper

Sci-fi action film starring Joseph Gordon-Levitt, Bruce Willis and Emily Blunt. In the year 2042, time travel exists but is available only on the black market. When the mob wants to kill someone, they send the target 30 years into the past, where they have employed a contract killer to eliminate them.

Joe (Gordon-Levitt) works as one of these mob hitmen, killing people whom the mob has sent back in time from the year 2072. But when he recognises one of the targets (Willis) as his own future self, Joe must figure out how to redirect the future and save his own life.
