Warner Bros. Pictures is time traveling Edge of Tomorrow, sharing two new images featuring stars Tom Cruise and Emily Blunt.

“The epic action of Edge of Tomorrow unfolds in a near future in which an alien race has hit the Earth in an unrelenting assault, unbeatable by any military unit in the world. Lt. Col. Bill Cage (Cruise) is an officer who has never seen a day of combat when he is unceremoniously dropped into what amounts to little more than a suicide mission. Killed within minutes, Cage now finds himself inexplicably thrown into a time loop—forcing him to live out the same brutal combat over and over, fighting and dying again…and again. But with each battle, Cage becomes able to engage the adversaries with increasing skill, alongside Special Forces warrior Rita Vrataski (Emily Blunt). And, as Cage and Rita take the fight to the aliens, each repeated encounter gets them one step closer to defeating the enemy“

USA Today talked to Cruise, who talked a needing to train extensively to deal with the visually impressive metal exo-suit that allowed for full movement but weighed 85 pounds on average.

“One of the suits with the angel wings had a sniper rifle and missile launcher on my back and weighed about 130 pounds. I’m having to sprint in it,” says Cruise, who helped develop the suits. “It’s physically grueling.”

In early days, the suit took as much as 20 minutes to even get into before the film team fine-tuned the design (“in the end we timed it and to get me into the suit took 30 seconds,” says Cruise). And actors even had specially made rigs on set to take the weight off their shoulders between takes.

Despite the physical demands, the futuristic apparel was striking enough to set the fights and stunts around “what worked and what looked cool with the suits,” says Cruise.

In theaters January 6, 2014 from director Doug Liman, the trailer will be released tomorrow.
