Buzz Lightyear's voice is one of reason, one with a rich timbre, one that belongs to Tim Allen.
I couldn't imagine him any other way but that things were almost completely different! Originally, Pixar approached Billy Crystal (Miracle Max, himself) for the role.
He said no but they wanted him so badly that they took lines from 'When Harry Met Sally' and animated them to show him.
Fortunately, the answer was still no....cause this is so weird.
