Zoe Bell is a professional stuntwoman who has done everything from Xena to Uma Thurman's character in Kill Bill. She's definitely on my list of 'if i could be someone else for a day' people.
Check out these cool clips of her work....
This one is from Quentin Tarantino's DeathProof. Zoe plays herself and does all her own stunts. I love this scene!
Here is another video of a bunch of stuff she's worked on.
