Mary Elizabeth Winstead
Best known for: "Scott Pilgrim vs. the World," "Live Free or Die Hard"
Why: She's a genre fan favorite already, she's an amazing actress (rent "Smashed") and if Whedon and Marvel decide to go in a non-European direction for Wanda she's one to watch for.
Why not: Can Winstead pull of the seductive side of Ms. Maximoff?
