Steve Rogers (Chris Evans) continues his acclimation to 21st Century society in the Marvel Phase Two sequel Captain America: The Winter Soldier, where he teams up with allies old (Scarlett Johansson as Black Widow) and new (Anthony Mackie as The Falcon) to stop his former friend Bucky Barnes (Sebastian Stan), who has transformed himself into the villainous Winter Soldier. Marvel Studios has released four new photos from this highly-anticipated follow-up, featuring Chris Evans and Anthony Mackie in action, along with directors Anthony Russo and Joe Russo. Take a look at these photos, then read on for more details from Chris Evans and producer Kevin Feige including on-set injuries, Steve Rogers' moral compass and the sequel embracing the tone of the comic books. And old fans rejoice, the iconic original WWII costume is back in action!

Although he has starred in the action-packed Marvel Phase One movies Captain America: The First Avenger and Marvel's The Avengers, Chris Evans revealed this sequel took the biggest toll on his body.

"I've been more hurt on this movie than I ever have. I haven't broken a bone, but you get hurt. There was a bunch of fight sequences on this movie where you're like, 'Wow, I just destroyed my knee today doing the same roll four or five times,' but nothing that ice and Advil can't fix, I suppose."

The actor also talked about Steve Rogers' getting acclimated to the 21st Century, and how that affects his moral compass.

"For Steve, it's about what is right. He's relatively acclimated to the modern day - it's not tech shock anymore, he's not just like, 'What's a cellphone?' It's more about, given his situation, given the company he works for, what are we doing that's the right thing? How much privacy, civil liberties are we willing to compromise for security? It's pretty crazy how relevant it is right now."

He also spoke about Cap's relationship with Anthony Mackie's The Falcon, and how they first meet.

"Meeting Mackie's character, he used to serve, now he works at the VA counseling guys who come home with PTSD - they connect on that level. I think they're both wounded warriors who don't bleed on other people. Cap has no one to bleed on. I think Mackie knows how to handle people like that. Sometimes when things are bad, trusting a stranger is the way to go."

Producer Kevin Feige talked about the time jump that Steve Rogers experiences, from the 1940s all the way up to present day, which is altered from the Marvel comic books in the movie, but still captures the same tone.

"We loved that idea of embracing the conflict that Steve has had in the comics from the moment he thawed out and woke up in the mid-'60s. Imagine that, going to sleep in the 1940s and waking up and you've got the JFK assassination and MLK and RFK and Woodstock and Watergate. Clearly, we're not doing any of that stuff, but we're embracing the tone of those comics."

The producer also talked about hiring comedic specialists Anthony Russo and Joe Russo to direct a big-budget superhero movie.

"You don't have to have directed a big, giant visual-effects movie to do a big, giant visual-effects movie for us. You just have to have done something singularly sort of awesome."

Chris Evans added that the directors' style matched Captain America's abilities.

"(Captain America) doesn't fly, he doesn't shoot lightning or anything like that. It's this very meat-and-potatoes approach to super powers."
