Bobby Driscoll, the voice of Peter Pan. His story is tragic. He was a child star, and afterwards, other kids made fun of him, he became a drug addict by 17, and he died at 31:( I love this movie, and this was depressing and kind of ruined my childhood. I still love Peter Pan no matter what though.
In 1968, two boys playing in a deserted and rat-infested tenement found the body of a 31yo drug addict, surrounded by religious pamphlets and empty beer bottles. Not until 19 months later was the body identified as that of child actor Bobby Driscoll, Academy Award winner and voice of Peter Pan. He was a Lost Boy after all.
