Bruce Willis and Joseph Gordon-Levitt are two sides of the same coin, as they say. The pair play the same character at different points of his life in Looper. The film’s first trailer has arrived from director Rian Johnson with its mind-blowing premise. In the future, time travel exists and is only used by those on the wrong side of the law. When they encounter someone who is a problem, they send them back in time to be assassinated by Gordon-Levitt’s Looper -- an individual whose sole job is to kill those from the future.
