William Edward "Billy" Crystal is an American actor, writer, producer, director, comedian, and television host. He is best known for his roles of Miracle Max in The Princess Bride, and Harry Burns in When Harry Met Sally.
He was the first to be offered to voice Buzz Lightyear in Toy Story, but turn down the role afterwards. After seeing the finished film, he said the decision was the biggest mistake of his career. However, Pixar took some lines from the coffee table scene from the film When Harry Met Sally and used his voice in some early test animation footage before Tim Allen was casted as Buzz.
