20. KIRSTEN DUNST

This year, for the first time, we were able to see her as more than "the girl from Spider-Man." Kirsten's role in Melancholia has been one of the most raved-about of the year and earned her a slew of acting nominations from film academies across the globe. With three more major, non-comic book movies on the way in 2012, we imagine that things will only get better for her.
