Turns out, Toy Story director, John Lasseter, actually wanted Billy Crystal as his first choice to voice Buzz Lightyear. Crystal even recorded a demo for Buzz in a very early stage of the production – I can only imagine how different the movie would have been without Tim Allen. He said that it’s his only regret in the industry of a role he turned down. Check it out.
I think I prefer Billy Crystal in Monster’s Inc.
