Joseph Gordon-Levitt and Bruce Willis star as younger and older versions of the same man in “Looper,” a time-travel action adventure that starts out interesting and becomes less so as it goes. It’s one of those futuristic movies in which, only thirty years from now, American life has become unrecognizable. The country is divided into five “zones” (it’s always zones in
these pictures). Time travel is possible, but has been banned by the government. Oh, yeah, everybody’s downtrodden, but you knew that, right?
