A day after Samuel L. Jackson let the cat out of the bag that Elizabeth Olsen will be playing the Scarlet Witch in Avengers: The Age of Ultron, Latino Review is reporting that Wanda Maximoff's brother Pietro, a.k.a. Quicksilver, has been cast, too.

The speedster will reportedly be played by Aaron Johnson, who already has a superhero pedigree with his starring role in the Kick-Ass franchise. This marks the second actor to be cast in the Quicksilver role -- essentially concurrently -- as Evan Peters is set to star as the same character in Fox's X-Men: Days of Future Past.

Johnson recently spoke to Total Film about what the role means:

He has real anger frustration – I like that. I always thought it’d be quite funny if you saw him eating loads and people asked him why and he’d explain it’s because he’s burning so much energy all the time. Or ideas that you’d see him come back round – but he’s already nipped out and got his lunch somewhere else. He just got bored – his attention span is so f**king quick.

It remains to be seen how Disney and Fox will differentiate their versions of Pietro Maximoff in their respective onscreen depictions. The character is sure to be linked with his comic book father Magneto in Days of Future Past, but it remains to be seen whether or not Disney will play up his parentage as Fox more or less has the movie rights to Marvel's merry mutants. Some fans have speculated that the Inhumans' Terrigen Mists might be at work, but it'd probably be just as easy to offer a simple non-explanation in a movie universe that includes Asgardians and the Hulk.

The Joss Whedon-directed Avengers: Age of Ultron is set for release May 1, 2015.
