The world is all new to him that I think maybe influenced that. I never thought about that. In other ways, Tarzan physically in terms of his physical maturity and his sense of himself as an animal is very developed and very mature and yet his sense of himself as a civilized man is, he's a baby. He's till very much on the boy side in terms of his emotional development vis a vis his father and mother. He's still a kid, with Terk and all the others.
Life is a playground.
Then he goes through certain rights of passage he has to kill Sabor. That's a big thing in terms of that world. That's his becoming a man. Those are questions you don't want to ask yourself, playing Tarzan. The yell was very hard.
