The filmmakers revealed that they are aiming for a 70s thriller vibe, akin to Three Days of the Condor. However, there are plenty of action sequences, and Joe Russo revealed that Marvel is the best place to go all out with the fight sequences.

"There's nobody better at that kind of stuff than Marvel if you're going to attempt to pull that off and go for it. We all tried to up the ante with what happens in this movie in terms of what's come before, and I think we've done that."

Joe Russo talked about Sebastian Stan as Cap's former friend Bucky Barnes, who becomes The Winter Soldier, praising the character's comic book arc conceived by Ed Brubaker and Steve Epting.

"He's an amazingly drawn character. He's so well conceived. It's one of the best comic runs in the last 20 years, one of our favorite comic runs of all time, and we really want to do it justice. It was important to us to make sure he just jumped off the page to the screen."

Samuel L. Jackson also teased that some former enemies have now become allies in this Marvel Phase Two sequel.

"Some of the people who used to be our enemies are now our allies. (Captain America is) trying to figure out, 'Well, how do we trust those guys?' or 'How do we trust the guys that you didn't trust who don't trust you?' And explaining to him that the black and white of good guys/bad guys has now turned into this gray area."
