It ain't easy being from the past.
One of the most notable things we didn't get to see in the final cut of Marvel's Avengers was how Steve Rogers was dealing with being a man out of time. And one of the reasons we didn't see that struggle was specifically because Marvel wanted to save that character growth for Captain America: Winter Soldier. Captain America himself, Chris Evans, delves into this very topic in an interview with Empire Magazine:
In The Avengers we had so many characters you have to address, you don’t really have time to sit with any single one. In this movie there’s a lot going on for Steve. He’s trying to acclimatize to the modern world. I don’t want to give too much away, but it’s about trying to find how he fits. He’s a man from the 1940s. He’s just woken up. For everybody else, it’s been a slow burn to get to where we are in 2014. But for him, suddenly there’s the internet, cellphones and The Patriot Act. The technology’s new to him and so is the access the government has to that technology.
The emphasis there is mine. Thinking about Rogers as a character, I find myself wishing I could recommend he read a copy of Philip Roth's American Pastoral, which deals specifically with a former all-American war hero's struggle with the Vietnam War (and his daughter's involvement in it).
Steve Rogers is a man gifted with great power, but Winter Soldier seems as though it will force him to question what defines too much power. He may find himself struggling with the title Captain America. Certainly the style of film Evans describes suggests that.
The [Russo] brothers said right from the start that we were really doing a ’70s thriller. And I think just Cap’s abilities mesh well with that kind of genre. I mean, his powers are very meat and potatoes. Faster. Stronger. Punch. Kick. That works with those types of movies. It would be more difficult to put, say, Hulk in that kind of context.
The '70s certainly liked its action flicks from a counter-culture perspective. So while there will be a lot of punching and kicking, we can no doubt expect some intriguing takes on international affairs as well.
