The film -- starring Robert Downey Jr., Chris Evans, Scarlett Johansson, Chris Hemsworth, Jeremy Renner, Samuel L. Jackson and Mark Ruffalo -- hits theaters May 4, 2012
Chris Evans' character awakens in the film for the first time since WWII. "It's just about him trying to come to terms with the modern world," the actor (photographed with Chris Hemsworth as Thor) tells EW. "I think in the beginning it's a fish out of water scene, and it's tough. It's a tough pill for him to swallow."
