Quicksilver and Scarlet Witch casting ideas for 'Avengers 2'
A chance for Marvel to improve the franchise's pedigree
Best known for: "Harry Potter" series
Why: Felton grew up playing a snarky, white-haired, jealous and misunderstood character in the "Harry Potter" franchise. Pietro is just an adult version of Draco Malfoy with super speed and a (sometimes) unhealthy need to protect his sister. It also doesn't hurt that Felton just happens to completely resemble how Pietro's been rendered over the years.
Why not: On the one hand, it may be typecasting for Felton, but he also may just be too young to play the role.
