"Inception" star Leonardo DiCaprio at No. 1 isn't a surprise -- but the little-known actress who came in at No. 2 is.

Leonardo DiCaprio was 2010's top-grossing actor, according to Forbes, with box office blockbusters Inception and Shutter Island earning $1.1 billion worldwide.

Mia Wasikowska came in at No. 2 thanks to her role in Tim Burton's Alice in Wonderland, which earned $1.03 at the box office.

Wasikowska topped Johnny Depp, her co-star in Alice, because her second film of the year, The Kids Are All Right, out-grossed Depp's soft The Tourist.

No. 4 is Robert Downey Jr., whose films, Iron Man 2 and Due Date, banked $808 million at the box office, and Daniel Radcliffe in Harry Potter and the Deathly Hallows Part 1, which nabbed a $780 million take at the global box office.
