The dynamic between Sam and Bucky was only seen briefly in Marvel Studios’ Captain America: Civil War, but was a hit with fans nonetheless. That likely led to The Falcon and the Winter Soldier being developed in the first place for Disney+.
After The Falcon and the Winter Soldier, there isn’t much known about where Sam Wilson and Bucky Barnes will end up as characters. Obviously, this series is leading up to Sam Wilson claiming the shield once and for all as the new Captain America, but it’s up in the air where Steve Rogers’ oldest friend will end up.
During an interview, John Nania, Sebastian Stan’s stuntman, talked about his career as a stunt performer and coordinator. When asked how much longer he would continue to do stunts, Nania mentioned how he wants to perform in front of the camera as long as he can before transitioning completely as a stunt coordinator. “I’ve still got a lot of performing left in me, and there’s still a lot of things I want to do,” he said. “I don’t think the Winter Soldier is quite over with in the Marvel [Cinematic Universe], there’s still a lot more to ride out on that one, and I look forward to being part of it.”
Nania seems to believe that he will continue as Sebastian Stan’s stunt double for Bucky Barnes in a future project, but doesn’t say more than that.
