Trivia / Heathcliff and the Catillac Cats

  • Author Existence Failure: According to some members of the show (see below), the show was cut short due to Mel Blanc's failing health. Curiously Blanc still performed several voices after the series up until his death however.
  • 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 (The Ren & Stimpy Show and The Ripping Friends) considered the show to be just another mediocre '80s series. Scott Shaw!note  (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) found this show beneath him because he hated cartoons. Eddie Fitzgerald (Tiny Toon Adventures, the basis for Pinky and John K.'s protege) doesn't remember ever working on this show (even though his name is in the credits).
  • International Coproduction: Between DIC Entertainment (USA and France) and TMS Entertainment (Japan) for the first season.
  • Keep Circulating the Tapes: Various DVD compilations were released in the mid-2000s which are now out of print. Shout! Factory released the first 24 episodes before losing the rights to the series. Mill Creek Entertainment released the entire first season on DVD, one half in 2012 and the other half in 2013. Finally averted in August 2016 when Mill Creek released the entire series on DVD, including the previously unreleased second season episodes.
  • Off-Model: Sometimes, Wordsworth's skates would disappear from his feet in between shots; it's especially noticeable at the start of the episode "Junk Food". In Season 2, Hector's ears would sometimes be colored beige (they're normally black), and then there's Cleo where sometimes her entire being was drawn horribly, such as in the episode "Hector's Takeover".
  • Screwed by the Lawyers: Ever wonder why Heathcliff and Riff-Raff never meet outside the end credits? Heathcliff's owners at the time, the McNaught Syndicate, apparently didn't want characters not created by them appearing with Heathcliff, so hence Riff-Raff and Cleo were both unable to appear; Hector, Wordsworth, and Mungo were created specifically so they could appear in both segments.
  • Talking to Himself: Riff Raff and Wordsworth were both voiced by Stan Jones, and then there's Mungo and Leroy, both voiced by Ted Ziegler.
  • Urban Legend of Zelda: Often times, someone will claim, or swear they saw an episode where Heathcliff and Riff Raff actually meet, but the episode only aired once for whatever reason. No such episode was ever made; the only time the two characters interacted was during the end credits and an odd cameo from Riff Raff in the comic strip.
  • What Could Have Been: Per an interview with voice actress Donna Christie, the show would've had more than two seasons had it not been for Mel Blanc's failing health.
