7. David Bowie
David Bowie has always been a theatrical dude both in his music and his performances, so it makes sense that he would lend his dramatic talents to acting. In fact, at the same time he was developing what would become his breakthrough musical work, he was also trying to make it as an actor, painter and mime. Not only did Bowie find success on Broadway, but he also did so on the silver screen with parts in films like Labrynth, and later Zoolander and the SpongeBob Squarepants movie.
