Quotes about The Beast

  • For some reason the creation was called a rhedosaurus, and although I can't remember where this name came from, I suspect Hal Chester or one of the writers coined it. Over the years, people have suggested that the first two letters relate to the initials of a certain animator. I have no comment.
  • The task of instilling pathos into a creature that was, after all, an innocent victim of circumstances was something I had set myself from the outset, although I was restrained by the script... The Beast is a poor lost soul brought back to life by man and then destroyed by man. If it sounds familiar, it is. King Kong was a huge influence, as he would be in all the other creatures I would be father to.
