Who played Boo Radley in 1962 To Kill a Mockingbird?

"Mockingbirds" in this story are those people characterized by their innocence which is taken away by exposure to some (unnecessary) evil. Boo Radley most definitely fits this description.

Arthur "Boo" Radley is an enigma, purportedly once a bright young boy who, as the result of some past event, had been sequestered away and emotionally damaged by his domaneering father for most of his life. He grew to be a misunderstood recluse - though he never lost his kindness. Indeed, it was his humanity that ultimately brought him back out of the house to help and later save the lives of young Scout and Jem.

It is Boo's kindness without prejudice, what me know as "innocence," that makes him a mockingbird. In spite of everything, Boo gives with all his heart, just as Miss Maudie explains to scout that a "Mockingbird sings with all its heart." To injure him, as "To Kill a Mockingbird," would simply be a sin.
