1,500 of them were in the movie American Gangster.
They've been in the movies Iron Man 2, Salt, Alvin and the Chipmunks, Spiderman 3, Memoirs of a Geisha, Dodgeball, Million Dollar Baby and many more. You've looked at them but never seen them. They work in Hollywood, and they're all fake. They're cheap extras who don't complain. And you have to blow them up before they'll go to work.
