In this exclusive behind-the-scenes clip from the film, Scarlett Johansson, Elizabeth Olsen and Emily VanCamp explain where their characters are in the latest installment of the Marvel Cinematic Universe.
Johansson, reprising her role as Natasha Romanoff (aka Black Widow), finds herself caught in the middle of the feud between Captain America (Chris Evans) and Iron Man (Robert Downey Jr.).
"Natasha is a bit torn between either side," she explains. "With Cap they really have a relationship where she wants to reason with him. But she sees Tony as a path of least resistance."

VanCamp's character, Sharon Carter (aka S.H.I.E.L.D.'s Agent 13), will play a larger role in Civil War than her appearance in 2014's Captain America: The Winter Soldier, where she spent most of her time undercover as Cap's literal girl next door.
"I'm really glad to be a part of it," VanCamp says. "Sharon Carter, she's a little sassier. We get to do a little bit of fighting in this, it's awesome."
Olsen returns as Wanda Maximoff (aka Scarlet Witch), and after her villainous turn in Avengers: Age of Ultron, this will be her first full film as one of the good guys – and one of S.H.I.E.L.D.'s most powerful superheroes.
"What I like about Wanda is the idea of her being terrified of her own abilities, it's really fun to play with," she explains.
In addition to the exciting new opportunities for her character, Johansson adds that she's equally thrilled to team back up with Civil War's all-star cast.
"There's been a few moments where you kind of look around and go, 'Oh I'm in good company. This is rad.' "
