The Top 10 Highest-Paid Actresses

It's not easy to be successful in Hollywood as an actress these days -- the competition is pretty fierce. Making it big is defined in a few different ways, from winning the best awards to getting the best parts to making the biggest money. And although careers go up and down on a dime and everything can change overnight, somebody has to be making the biggest money of them all. That somebody right now? Reese Witherspoon.

She's doing well for herself, earning between $15 and $20 million per movie -- despite her latest work "Rendition" not doing all that well in theaters. And she's in good company, too, with actresses like Cameron Diaz, Julia Roberts, and Jody Foster joining her in the ranks of the top 10 highest paid actresses.
