Even after the events of The Avengers Captain America still has some adjusting to do with the modern world. Speaking with Entertainment Weekly, Marvel Studios President Kevin Feige gave some insight into the setup for the upcoming sequel Captain America: The Winter Soldier.
“We weren’t going back to World War II. Cap cannot travel in time. So while Tony can go home to Malibu and Thor goes up to Asgard and Hulk can sort of ride the rails, Cap was stuck.
“So Cap does stay with S.H.I.E.L.D. because he has nowhere else to go. But he’s not necessarily comfortable there. As you might imagine, somebody who’s spent 70 years in ice, frozen, wakes up and has to fight a bunch of aliens with a bunch of weirdos—he is trying to figure out what his life is. “
“And just as he’s given permission to let go of the past and to focus on the modern world, a ghost comes up…. With the Greatest Generation in World World II, there’s a tendency to reflect on that period and say, ‘Things were black and white back then, and now it’s hard to know who the bad guys are.’ ‘We wanted to play on that a little with Cap being uncomfortable with the way S.H.I.E.L.D., and in particular Nick Fury, operates.”
