Movie rights are complicated business, especially when it comes to characters from Marvel’s vast mythology. However, by some crazy loophole, Quicksilver and the Scarlet Witch are able to appear in films produced by Fox and Marvel Studios. That’s why despite seeing the silver-haired speedster in this year’s ‘X-Men: Days of Future Past’, Pietro Maximoff will also show up in ‘The Avengers: Age of Ultron’ next year. But what will be the difference between the two characters other than two different actors? Kevin Feige has the answer.

While speaking to IGN, the Marvel Studios president mentioned that measures were taken to ensure that Evan Peters’ character in Bryan Singer’s triumphant return to the X-Men movie franchise bares little resemblance to Aaron Taylor-Johnson’s role in Joss Whedon’s follow up to 2012’s ‘The Avengers’. Although they may have the same set of powers and similar visual effects may be used, it’s Marvel’s plan to focus on different aspects of Quicksilver’s core being:

“We are very much playing up two things that [Days of Future Past doesn’t] play with: one is his relationship with his twin sister, Wanda; the other is, his backstory as an Eastern European child of a war-torn country, and we follow him throughout the whole movie — him and Wanda — as it relates to their feelings about the Avengers and how that shifts and changes over the course of the movie. So it’s a very different thing than coming out from one, unbelievably awesome showcase sequence of the movie, and much more interwoven throughout the entire movie.”

In other words that aren’t meant to be a knock on Singer’s take, the biggest difference will be a character arc. While we all loved Quicksilver’s scene-stealing appearance in ‘X-Men: Days of Future Past’, we still only got to see him in that one scene. Whedon’s version appears to be a much bigger part of ‘Age of Ultron’, so that offers the chance to get to know him a bit better and see him evolve.
