Quicksilver and Scarlet Witch casting ideas for 'Avengers 2'
A chance for Marvel to improve the franchise's pedigree
Best known for: "Looper," "The Devil Wears Prada"
Why: Like many of the actors in "The Avengers" cast, Blunt has displayed a tremendous versatility. From comedies ("Prada") to period pieces ("The Young Victoria") to Sci-Fi ("Looper") to intimate dramas ("Sunshine Cleaning") to studio family flicks ("Gulliver's Travels") she's shined in almost everything she's chosen (even when the material she's been given is lacking). Could she make her mark among the scene stealers in this superhero acting troupe? Absolutely.
Why not: Unless Marvel decides to go incredibly young with the character it would be surprising if she wasn't in the final mix.
