Jennifer Lawrence$34 millionWho says women can’t be action heroes? Just 23 years old, Lawrence is proving that women can be as big a draw for blockbusters as men. “The Hunger Games” is the most successful young adult franchise since “Twilight” and her recent turn as Mystique in “X-Men: Days of Future Past” helped make the movie the highest-grossing of the franchise. Combine that box office prowess with three Oscar nominations and one win and you have the most powerful actresses in Hollywood.
