* ActorAllusion: Who knows if this was on purpose, but as Phil is an Expy (or at the very least an AffectionateParody) of Mickey from the Rocky films, [[Film/BatmanReturns this isn't the first time Danny DeVito has played a character made popular by Burgess Meredith...]]
** In one episode of the TV series, Creator/DanCastellaneta voices a [[Literature/TheOdyssey certain reporter]] named [[WesternAnimation/TheSimpsons Homer]].
* AllStarCast: The TV series. The question isn't finding characters voiced by known/famous actors, but finding characters who aren't. Look up a voice actor's list. It's just oozing with famous titles. It all came up to be because James Woods wanted to return and thus most of the original cast jumped along, and others got interested.
* CastingGag: In the animated series.
** A recurring villain on the show was Echidna "the mother of all monsters" voice by Kathy Lee Gifford. In one episode, Hercules accidentally used one of Zeus's thunderbolts to destroy the mountain imprisoning her husband Typhoeus, voiced by her old talk show partner, Regis Philbin.
** Creator/MervGriffin appears as a gryphon with a talk show.
*** [[Series/TicTacDough Wink]] [[Series/HighRollers Martindale]] (who worked with Merv on ''Series/HeadlineChasers'') was a riddle-giving Sphinx.
** "Hercules and the Dream Date" has a guest character in Galatea, Hercules' date for the Aphrodesia Dance, who's [[ClingyJealousGirl completely obsessed with him]]. Galatea was voiced by Creator/JenniferAniston, who was dating Tate Donovan at the time.
** Creator/WilliamShatner as Jason in "Hercules and the Argonauts", because who better to play the captain of the Argos than the captain of the [[Franchise/StarTrek Enterprise]].
* CutSong: Hercules had a ballad called "Shooting Star", and there was an alternate, slower song for Meg called "I Can't Believe My Heart".
* DoingItForTheArt: In regards to James Woods' performance as Hades. Woods has said that the role is his absolute favorite in his entire career and gladly reprises the role whenever asked, be it for the ''Franchise/KingdomHearts'' series or a few bumpers at the Disney theme parks!
* GeniusBonus: Pain is right, rabbits aren't rodents; they're lagomorphs.
* KeepCirculatingTheTapes: One VHS tape, "Zero to Hero", was released. It is basically an expanded version of the episode "Hercules and the Yearbook", with roughly three full episodes to fill out the time. It served as a pilot for the series. The rest of the series has not been released on any home video format.
* MissingEpisode: At least four episodes were removed from rotation following 9/11, most notably ''Hercules and the Hostage Crisis'' which involved ''terrorists'' taking over Prometheus Academy, which was almost identical to the Columbine High School massacre.
* TheOtherDarrin[=/=]PoorMansSubstitute: Most of the movie's cast ''did'' return for the series, except for Charlton Heston, Rip Torn, and Danny [=DeVito=].
** An unusual, marginal example: Tate Donovan returns as Hercules, but he portrays the younger version of the character, who was voiced by Josh Keaton in the movie.
** Amanda Plummer (the voice of Clotho, one of the Fates) was replaced by Creator/TressMacNeille.
* PlayingAgainstType: Non-acting example: The art director was Gerald Scarfe, the same person behind the nightmarish [[DerangedAnimation animation]] of ''Music/TheWall''.
** And another one: Disney veteran Andreas Deja was asked to animate Hades, but he feared that animating ''another'' villain (he'd already done a considerable streak of famed villains, animating [[Disney/{{BeautyAndTheBeast}} Gaston]], [[Disney/{{Aladdin}} Jafar]] and [[Disney/{{TheLionKing}} Scar]] one after the other) would be too easy and obvious. So, to challenge himself, he asked to animate a hero instead and was given the job of animating Hercules himself.
* TheRenaissanceAgeOfAnimation: ''Hercules'' is considered a lower point in this era.
* RetroactiveRecognition: Idina Menzel was already pretty well-known in the late 90s thanks to ''Theatre/{{Rent}}'', but her guest spot as Circe in the show is even funnier now, since she went on to appear in [[Film/{{Enchanted}} two]] [[{{Disney/Frozen}} later]] Disney movies.
* SoMyKidsCanWatch: The reason both Creator/DannyDeVito and James Woods joined the cast. Woods enjoyed playing Hades so much he agreed to play the voice for any future Disney animation or video game projects.
* WhatCouldHaveBeen:
** Jack Nicholson was offered the role of Hades, but he turned it down.
** John Lithgow meanwhile, accepted the role and recorded lines, but Disney found he didn't have the right balance of menace and comedic timing they were looking for.
** A bit of a HilariousInHindsight once you know that James Woods was offered the role of TheJoker, the role that Nicholson played, in the [[Film/{{Batman}} 1989 Batman film]].
** Hades was originally written to speak more slowly and menacingly, but Disney liked Woods' take on him so much that they changed the character and as a result almost every scene he was in.
** Donny Osmond auditioned for the role of Hercules but Disney thought his voice was too deep for Herc.
** In the Animated Series spin-off, Persephone, who only appeared in background cameos, originally was conceived to be the ''daughter'' of Demeter and Hades and they were in a bitter custody dispute. The idea got scrapped.
** The original pitch for the movie was going to be more mythologicaly accurate with Hera as the BigBad the titans as both the collective BiggerBad and TheStarscream with Hades as something of a sidekick to Hercules
*** This concept was later used for HerculesAndXena.
** Meg was initially going to be a bit more of a DamselInDistress, but since she spent so much time with Hades, when he became a car dealer Susan Egan made her a much stronger woman just from the amount of improv she had to deal with.
