I could have sworn I'd posted to an old version of this list, but at some point, I couldn't log back in (I never posted here that often). Anwyay, there's a few misattributions regarding the human actors in "Don't Eat the Pictures." Paul Dooley played the guard, James Mason was Osiris, Fritz Weaver was the scroll reader or whatever that character was called, and Aram Chowdhury, a then seven year old child actor, was Prince Sahu. Chowdhury later died (I recall coming across an obit, which is how I first found the info.
And the full name of Jack Warden's editor character in "The Great Muppet Caper" is Mike Tarkanian, as listed in cast lists and on his nameplate.
