Hollywood's top-grossing stars: DiCaprio, Depp and ... Mia Wasikowska?

The biggest movie stars of 2010 in terms of box office have a bunch of names you'd expect -- Leonardo DiCaprio, Johnny Depp, the "Twilight" kids -- and one that you probably wouldn't guess: Mia Wasikowska.

You may know Wasikowska better as Alice, the title character in Tim Burton's "Alice in Wonderland." Thanks to that movie's billion-dollar worldwide take, she's currently tied with Depp for second place on Forbes' list of the top box-office earners of 2010.

No. 1 on the list for the year is DiCaprio, who starred in "Shutter Island" and "Inception," which between them earned $1.1 billion this year. Depp and Wasikowska each have $1.03 billion to their names, with nearly all of that coming from "Alice in Wonderland." The part after the decimale point coming from "The Kids Are All Right" (Wasikowska) and "The Tourist" (Depp), both of which have made about $30 million. Depp will take sole possession of second place by the end of the year as "The Tourist" continues in wide release.

Also of note: 12-year-old Jaden Smith ranks ninth on the list thanks to "The Karate Kid," which made $359 million worldwide. He's tied with his co-star, Jackie Chan.
