<Li> Aaron Taylor - Johnson as Pietro Maximoff / Quicksilver : The twin brother of the Scarlet Witch , who can move at superhuman speed . Taylor - Johnson felt Pietro was defined by the fact that he and his sister were abandoned by their family , and they both had to grow up `` in Eastern Europe defending and looking out for themselves and each other , '' that they both look to the other for guidance . Taylor - Johnson also said that Quicksilver was `` very overprotective '' of Scarlet Witch and has `` real anger frustration '' , which results in him being easily bored because of a short attention span . Feige stated exploring Quicksilver 's relationship with his sister and his backstory growing up in Eastern Europe would help differentiate the character from Evan Peters ' version in X-Men : Days of Future Past ( 2014 ) . Taylor - Johnson stated that the running style for Quicksilver went through multiple iterations , saying , `` The running style we tested early on was just very one - dimensional and boring to look at , but if you try to do free running , like parkour , then that 's very much Captain America 's style ... You have to find your own place in the stunt world . '' Much of Taylor - Johnson 's scenes were filmed outdoors to give `` life '' to his running , as opposed to running indoors in front of a green screen . </Li>
