The Sword in the Stone

[Bill007]

I have a question for anyone who might know. The Sword in the Stone is a very good movie but one thing about it has always irritated me and that is the fact that Wart's voice keeps changing throughout the film. He goes from sounding like a preadolescent to a kid going through puberty, even within the same scene! Was there a reason for doing this or were they just being lazy? I know 3 different boys voiced the character but why did they have to use voices so painfully different? That's the one thing that keeps it from being one of my favorite Disney films.
I think they should consider redubbing it so the voice is consistent throughout. I know that means tampering with a classic but I'd rather see that than the disturbing voice changes throughout the film.
