* ActorAllusion:
** When the heavenly whippet looks in Charlie's records, his mother and father are named "Loni" and "Burt", and look like canine versions of Loni Anderson and Burt Reynolds (who were together at the time.) Loni also appears in the film as one of Charlie's "close friends".
** During his VillainSong, Red puts Carface in a barber's chair and proceeds to shave him, a clear ShoutOut to ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet''. George Hearn, who voiced Red, was also one of the many actors to have played the titular barber in the aforementioned musical.
* [[ActorAllusion Author Allusion]]: Don Bluth's birthday is also September 13, 1937. The idea that every human year is seven dog years is a myth -- Charlie is about 25. Even though he seems older.
* ActingForTwo: Annabelle and Belladonna are both played by Bebe Neuwirth.
* [[DuelingMovies Curb-Stomp Battling Movies]]: Released on the very same day as (and promptly slaughtered by) ''Disney/TheLittleMermaid.''
* TheDanza: Creator/CharlieSheen as Charlie in the sequel. Also an example of TheOtherDarrin, as Burt Reynolds was Charlie in the first film.
* ExecutiveMeddling: We were originally going to get to ''see Charlie's body'' flying off the pier (a rare example of a meddling executive making a good call). Interestingly, many book adaptations of Don Bluth films include unused artwork; ergo, the tie-in book for this film showed a very clear silhouette of Charlie's body flying alongside the car...
** Bluth also claimed that he was locked out of most of the recording sessions for the actors.
* UsefulNotes/FurryFandom: One of the most popular works amongst it and, along with ''TheSecretOfNIMH'', one of Don Bluth's ClosetKey's to it.
* HeyItsThatVoice:
** In the film that started it all:
*** Charlie Barkin is [[Film/SmokeyAndTheBandit Bandit]].
*** Carface is [[Series/{{Alice1976}} Mel]]. Kiss his grits.
*** Itchy is [[Film/{{Spaceballs}} Pizza the Hutt]], [[WesternAnimation/TheSecretOfNIMH Jeremy]], and [[WesternAnimation/AnAmericanTail Tiger]].
*** Anne-Marie is [[WesternAnimation/TheLandBeforeTime Ducky]]. [[CatchPhrase Yep, yep, yep!]]
*** King Gator is [[WesternAnimation/TheNightmareBeforeChristmas Oogie Boogie]].
*** Killer is VideoGame/{{Gex}}, [[WesternAnimation/RockADoodle Hunch]], [[WesternAnimation/SpongebobSquarepants The Dirty Bubble]], and a panelist on Series/MatchGame.
** In the sequel:
*** [[WesternAnimation/SpongeBobSquarePants Mermaid Man]] voices Carface in the sequel. And he's [[MemeticMutation EEEEEEE-VIIIIIIIIIIILLLLLL!!!!]]
*** Red is the original ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'' (see ActorAllusion above).
*** Sasha also sang some songs on ''WesternAnimation/PhineasAndFerb''; plus, she was Doofenshmirtz's ex-girlfriend in said show's episode "Chez Platypus".
** In the series, Annabelle is [[Series/{{Cheers}} Frasier Crane's wife Lilith]].
*** [[TalkingToHimself As it her evil cousin]].
** In Italy and Sweden, David was [[Film/{{Matilda}} Mikey Wormwood]].
* NonSingingVoice: In the first film. While Judith Eva Barsi was only Anne-Marie's speaking voice, the film developers had adult actress, Lana Beeson, to do the singing voice for Anne-Marie in the SugarWiki/{{heartwarming|Moments}} TearJerker song, "Soon You'll Come Home". Barsi did audition for the singing part but [[PaterFamilicide because she broke down in stress from events at home during the audition]], they didn't make her do the singing.
** Painfully averted with Burt Reynolds in the original and Ernest Borgnine in the sequels. It seems the only thing each incarnation had in common was giving songs to non-singers.
** Wonderfully averted with Sasha and Belladonna in the sequels, who were played by professional singers Sheena Easton and Bebe Neuwirth, respectively.
* TheOtherDarrin: Save for Dom Delouse and Charles Nelson Reily as Itchy and Killer, respectively, none of the actors from the first film are in the sequel or TV show.
* RealitySubtext: Consider the [[http://z7.invisionfree.com/thegangoffive/index.php?showtopic=981 circumstances]] surrounding Creator/JudithBarsi's untimely death. Now try to watch the film without cringing violently. This may also explain the FamilyFriendlyFirearms.
* TheRedStapler: Watching this movie WILL make you want to get a German Shepard.
* TropeNamer: For BigLippedAlligatorMoment, indirectly, through WebVideo/TheNostalgiaChick.
* TroubledProduction: The sequel, according to [[WordOfGod the directors]], was originally animated in Dublin, Ireland (where Bluth's original studio, which produced the first film, used to take place before that). But then, after Screen Animation Ireland, the Dublin studio in charge of the animation, shut its doors, the animation has to be outsourced to several studios in countries like Taiwan, Korea, Canada, and Denmark in order for the film to meet up the deadline.
* WhatCouldHaveBeen:
** Charlie was a detective in the original draft and the film was going to be an anthology of three short stories.
** The Hell sequence was supposed to be a lot longer than it was in the movie.
** In Don Bluth's book ''The Art Of Animation'', he claimed that Burt Reynolds, a foreigner to animation, originally wanted to give Charlie a broad, cartoonie voice. Bluth replied "We hired Burt Reynolds to do Burt Reynolds, not Scooby-Doo."
