The very title of Captain America: Civil War lends itself to the notion of friends vs. friends, but it’s a real doozy when Team Cap battles Team Iron Man in the new film (out May 6). Alliances shift, bad feelings are had, and you have awesome moments like the one in the first Civil War trailer where Steve Rogers (Chris Evans), aka Cap, and the Winter Soldier (Sebastian Stan), aka Cap’s childhood friend Bucky Barnes and former brainwashed Hydra assassin, throw down with Iron Man (Robert Downey Jr.).

Two against one may not be fair, but it’s sure fun to watch — and enjoyable to play, says Stan:

“It’s one of those days where the equivalent would be that scene in Apollo 13 when the astronauts come back and they’ve survived reentry to Earth and you cut to mission control and everyone’s like ‘Yeah!’ “

He admits that the scene, which had to be done in one take and involved well-choreographed fighting moves plus a bunch of shield sharing, took them just about 15 times to get right. Plus, there were times when Evans and Stan would be going through the scene without having Iron Man there at all just in case there needed to be CGI effects added in later. “Then you’re just fighting air, which is even more difficult.”

Stan’s looking forward to fans seeing Steve and Bucky — or as the Internet likes to call them, #Stucky — fighting side by side again with the added emotional layers of having to beat down Cap’s other friend from the Avengers.

“This is how I would look at it: It’s three people and they’re on a boat in the middle of the ocean, the boat is sinking and the boat may stay afloat with one less person on it. So who has to go? It’s inevitable at that point because blood will always win in the end, and (Steve and Bucky) are really like blood brothers.”
