Joe Russo: Talking about the kiss for a second. That was something that got picked out in the room - we were all like can we do it, can we not do it? It’s such an old trope.
Steve McFeely: Yeah, that’s true.
Chris Markus: Well, you know, it’s the debate of are they actually gonna - is there gonna be romance between them for real in the movie? And I think eventually we decided that there’s no time and it sorta sells both characters short, that the only reason you’d have the Black Widow is so that there can be sexual tension. But a kiss is always fun. Plus it leads to this conversation which really cracks Steve open.
Anthony Russo: Wonderful scene in the movie, Chris and Scarlett - you really see their chemistry here. This scene greatly benefited from their working history together, the fact that they know one another so well. I remember reading this scene before we shot it in the trailer with them.
Joe Russo: And making adjustments with them.
Steve McFeely: I think they tweaked it, the practice part - they wanted to put the practice line in.
Joe Russo: Right. So a lot of the bantering back and forth, the playing off of each other, came from the work in there. I think it was in Scarlett’s trailer we were all sitting around reading the scene, work-shopping the scene a little bit. But it’s great because it gives it a nice energy and a spark. And you know what’s interesting about this scene is the first time since The Avengers… which is this cultural phenomenon where you get to see two of the characters from that group behaving like friends. Or at least behaving in an intimate fashion and having a conversation - you know they’re talking about things other than saving the world.
Anthony Russo: What a pivotal moment in the movie narratively and on a character level for him to be looking for a friend and for her to tell him no.
