THIS SUMMER, "Men in Black 3" did time travel the silly way. Now, this fall, "Looper" will do it too - but it won't be all fun and games. From indie director Rian Johnson ("Brick"), "Looper" stars Joseph Gordon-Levitt (in some really strange aging makeup) as a time-traveling assassin in the year 2072, who gets sent back in time by the mob to kill the older version of himself, played by Bruce Willis. Piper Perabo, Jeff Daniels, Paul Dano, and Emily Blunt play supporting roles. Confused yet? It's high-concept stuff, but the action and the stars are bound to draw some audiences. The September release date doesn't bode well, but we think that a reasonable crowd will come out for this--we're betting on a healthy $15M at least.
