Creator Backlash/Old Shame: Although this show is often looked back with fondness and nostalgia for those who grew up in the 80s and early 90s, most of the people who worked on this show don't have very nice memories of it. John Kricfalusi considered the show as just another mediocre 80s series. Scott Shaw (Captain Carrot and His Amazing Zoo Crew!) found DiC too disorganized, one writer talked about Executive Meddling from Japanese animation producers (TMS, or rather their subcontractors, opposed wacky cartoonish gags), Chuck Lorre (Two and a Half Men) hated cartoons and found this show beneath him. Eddie Fitzgerald (Tiny Toon Adventures and John K.'s protege) doesn't remember ever working on this show (even though his name is in the credits).
Heathcliff was voiced by Mel Blanc (in what would be the last time Blanc would voice a new character, as he died in 1989). He is also known to fans for playing (among many others) Bugs Bunny, Daffy Duck, and Porky Pig.
