Dan Castellaneta has one of the most recognizable voices in the world, and it isn't even his own. It's Homer Simpson's, the character he voices for the Simpsons. Although he is most famous for that voice, he isn't limited to it; he is also known for Willie the Groundskeeper, Hans Moleman, Grandpa, Krusty and Barney. Among doing voices in cartoons, he is also a stand-up comedian, and an actor, which he has been doing since he was six. He got his big break though, when Tracy Ullman came to him with a request for him to work with her. He accepted, and even turned down a TV series to work with Ullman.
