Percival "C." McLeach IS George "C." Scott!
What I mean is: the disney villain, Percival C. McLeach is a character that looks exactly like the late actor George C. Scott, that's right, the same George C. Scott who plays McLeach's voice! The evil poacher even has facial expression like the famed Scott! I have compared pictures of McLeach and Scott and there is a BIG resemblence.
TRY IT!
Also look for the to-die-for John Candy as the voice of Wilbur the albatross!
