3. Saoirse Ronan
Saoirse Ronan (it's pronounced sir-sha by the way) haas more than proven her mettle across the board as both an impressive actress but also as a serious contender for an action heroine in her own right, having come off big successes in several major studio productions. She broke out in
Atonement, winning her a slew of critical praise and catapulting into the cinematic consciousness, followed by her central role in the highly-anticipated
The Lovely Bones movie adaptation. Best of all might just be her committed and utterly killer (literally) role in thriller
Hanna as the titular girl herself, a teenage girl trained to be an assassin by her dad, a role that proves she's more than a match for the Slayer's fighting prowess. Add all this to some delicious Marvel rumours that she might be up for playing the Scarlet Witch in Joss Whedon's eagerly-awaited sequel to
The Avengers, and Saorsie's star power could be the perfect thing to give a Buffy reboot some clout.
