Director Rian Johnson and Sony Pictures have released four new stills from their latest thriller, Looper. The film stars Joseph Gordon-Levitt and Bruce Willis as the same character, decades apart. The elder Willis lives in a world where time travel is possible while Gordon-Levitt’s present finds him an assassin for the mob. He’s not any ordinary killer, he murders people who are a problem for the mob in the future. They send them back in time, and Gordon-Levitt is waiting, shotgun in hand. But, what happens when he goes to pull the trigger on one fateful day, and the man staring back at him is Willis? Look for Looper September 28.
