Chris Markus: We always wanted to approach Sam through the prism of a being fellow veteran. Someone who could speak to Steve on that level as opposed to, you know, because he’s Captain America. And also we brought up the idea that Steve, in addition to everything else he’s gone through, spent four years in World War II. That’s very traumatic stuff. And he has never had a chance to decompress about any of it.
Anthony Russo: One of my favorite lines from him is, where he says: “I’m more of a soldier than a spy.” I just loved that so much because it speaks to his relationship with Cap and their nature.
Joe Russo: You guys did a great job with this scene. This is probably the hardest scene in the movie because it leads to the biggest buy in the film, which is - well, maybe there’s a couple of other big buys - that Cap is gonna go back to a guy he met jogging on the mall when his life is in danger because he’s the only guy he can trust. So it was important that these two connect on a very deep level, an emotional level in this scene.
Chris Markus: It’s always a credit to Mackie.
Steve McFeely: Yeah. I trust Mackie.
Chris Markus: You would go to Anthony Mackie. Some people you wouldn’t go to.
Joe Russo: Let’s talk about Mackie for a second. It’s a reason we cast him is one, you know, I’ve never not seen a truthful moment from him on screen, and two, he has this incredible ability to combine charm and integrity. A difficult thing to do is to be funny and convey integrity at the same time.
Steve McFeely: He’s not shallow.
Joe Russo: He has great depth as an actor which allows Steve to feel the depth, the audience to feel the depth, which makes you believe that Steve would trust this guy even though their relationship is so new.
