If you guessed Mia Wasikowska, you're right! The 21-year-old Australian actress tied her Alice in Wonderland co-star Johnny Depp for second place, both with "a total worldwide gross of $1.03 billion."
Behind them, Robert Downey, Jr. ranked fourth with $808 million thanks to Iron Man 2 and Due Date. Daniel Radcliffe brought up the caboose of this shortlist with a paltry $780 million from Harry Potter and the Deathly Hallows: Part I. Not listed: Reese Witherspoon. Better luck next year!
