The Russo Bros. did a little chatting about Captain America Civil War, and revealed to us when the movie takes place. When I say when, I mean how long after Avengers Age of Ultron it takes place.
We like to say that the amount of time that has passed in between films is the amount of time that has passed in the movies. So, it’s about that amount time. We find Cap leading the Avengers. He’s tutoring or mentoring Scarlet Witch in the beginning of the movie and bringing her into the fold. We find them on a mission at the start of the film. The effect that Ultron has had on everyone certainly is central to the storytelling of the movie. It’s very strong. We’re dealing with issues of collateral damage, imperialism, what rights do super heroes have to pursue villains across borders. It’s very politically minded. Cap’s dealing with all of that at the beginning.
