Quicksilver - Evan Peters, Aaron Johnson

Before both taking on the role of the super fast Quicksilver, Aaron Johnson and Evan Peters played normal, powerless high school students in the DIY superhero action-comedy Kick-Ass (2010). Peters’ American-raised Quicksilver was a major highlight of Bryan Singer’s 1970s-set X-Men sequel/prequel Days of Future Past (2014). While we've only seen glimpses of Johnson’s Quicksilver in action in trailers for Avengers: Age of Ultron, we do know that he will have an Eastern European accent. Other major differences have to do with the shared rights to the character between Fox and Marvel. Marvel can use Quicksilver and his sister Scarlet Witch, but their paternal link to Magneto can’t be mentioned. Also, in the Marvel Cineverse, the characters aren't mutants — you can read the spoilerish origins of their powers here. As for what Johnson thought of Peters' take on the character, he said in an interview: "I didn't watch any of it while making Avengers, but I did see it recently, and it was fantastic."
