"I never conceived of putting a voice on the thief," Calvert said. "That was a surprise to me. Whatever is wrong with the film, I'm sure someone will blame me for it."
Heh. Right you are.
(Calvert DID put a voice on The Thief in the WIP, sort of, giving him a Gollum like voice which is very odd. In Calvert's final version, Ed E. Carroll wheezes for the Thief, lending another creepy atmosphere to the scenes which I also find odd.)
