“We were just there on set because we knew there was gonna be no dialogue. We knew it was just gonna play back in the museum as silent footage of them together so we shot it, they were just talking to each other, not even as the characters, they were just talking to each other as Chris Evans and Sebastian Stan trying to make each other laugh and have a good time just so we have this little moment between the two characters. We actually never had a script in terms of what was happening there in a storytelling level, it was just a moment to show the two were close and had a great relationship.”
- Anthony Russo on what Cap and Bucky were talking/laughing about in the Smithsonian footage
Okay but when Steve looks up and meets Bucky’s eyes, Bucky squeezes Steve’s shoulder so tightly, pressing his thumb into Steve’s collarbone. He’s trying so hard to express something that he can’t say in words, something more meaningful than “I’m with you ‘till the end of the line”.
And as soon as Steve locks eyes with Bucky, he goes from amused smiling to something softer. Something that’s expressed more with his eyes than with his mouth. They have an entire conversation without words, of everything they feel but can’t say.
