Peter Mayhew
You might not know the name Peter Mayhew, but you probably know his character, Chewbacca from Star Wars. The actor previously appeared in a news article about men with huge feet (which makes sense, since he stands at 7'3"). Producers saw the article and knew he would be the perfect fit for playing the giant Wookie. He has appeared as Chewie in five of the films, though he also auditioned for Darth Vader.
