In Edge of Tomorrow, Lt. Col. Bill Cage, played by Tom Cruise, is trapped in a Groundhog Day-esque time loop as he lives and dies fighting against an apparently unstoppable alien threat. The only way out is for him to get better at fighting the invaders, and with each death comes new skills and experiences that will help him and Special Forces soldier Rita Vrataski (played by Emily Blunt) take the aliens down. The new trailer gives an even clearer glimpse of their plight, as Cage intones early on that he's been fighting this losing for "an eternity." Check it out when it hits theaters on June 6th.
