@imallentsai: Did you know that for MONSTERS, INC.... Before Billy Crystal was cast as Mike, he was actually offered the role of Buzz Lightyear in Toy Story. But he declined -- which he later regretted. Pixar then promised to tailor a role to him in a future film. But Billy told them to "do what's best for your movie -- and don't forget me when something good comes around." Years later, he received that call for Monsters, Inc.
