Bradley Cooper
This is one film that Bradley Cooper likely leaves off his resume—My Little Eye (2002). Inspired by the reality show Big Brother, Cooper plays Travis Patterson, one of the masterminds manipulating a group of adults spending six months locked inside of a mansion. Bradley's feature film debut had been one year prior in Wet Hot American Summer (2001), but the actor didn't achieve critical levels of success until 2009 in The Hangover.
