Captain America: The Winter Soldier Audio Commentary:
“This 1st act [of the movie] is all about him trying to find an identity. We wanted to give him some great character moments that really illustrated existential crisis that he’s going through. In no other movie could you have a character walking through their life at the Smithsonian. It happens to work for Cap’s Rip Van Winkle story, it happens to work for who he was in WWII, but it also puts him in a unique situation. He’s constantly asking, “Who am I?” Even his past is not his anymore, it’s history. Everyone here can go look at who he was. You really start to feel how alone and isolated he is, and that his life is gone. Even though he is an incredibly proficient fighter now, he has no identity, really doesn’t. He’s working for S.H.I.E.L.D., he’s got a relationship with Natasha and Fury, but it’s not substantial. And he doesn’t know who he is.”
