* AbilityOverAppearance: Some executives were skeptical of casting Ryan Gosling as Hercules since he was so skinny (whereas Kevin Sorbo was brawny), but Gosling won them over with his performance.
* ActorAllusion:
** In "In Your Dreams," Cheiron knows a fair amount about Morpheus and the dream realm. A few years earlier, Nathaniel Lees played a priest of Morpheus in "[[Recap/XenaS01E03Dreamworker Dreamworker]]" on ''Series/XenaWarriorPrincess''.
** In "Get Jason," Paul Norell plays Buterus, an assassin who infiltrates the Academy by pretending to be a cook. On ''Series/HerculesTheLegendaryJourneys'', Norell played Falafel, a recurring LethalChef.
* DawsonCasting: Inverted with Ryan Gosling. He was 17 when cast, but Hercules was 18.
* DuelingShows: Came about just as TV show version of Disney's WesternAnimation/{{Hercules}} was airing as well.
* ExecutiveMeddling: Fox opposed any major serialization, but they did allow some episodes to be linked (such as the Amazon and Bacchus arcs).
* IronyAsSheIsCast: Ryan Gosling is a famously skinny guy, playing one of the great strongmen of legend.
* KeepCirculatingTheTapes: Unlike its parent series or ''[[Series/XenaWarriorPrincess Xena]]'', ''Young Hercules'' spent many years under this trope (though it had been available in its entirety on Hulu for some time); this was par for the course as far as Fox Kids series went (Universal's ''[[WesternAnimation/WoodyWoodpecker The New Woody Woodpecker Show]]'' has suffered the same fate). The trope was finally averted in 2015, with Creator/ShoutFactory releasing a complete series set and individual volumes.
* ProductionPosse: The Lewalds hired several writers they have worked with before, such as Mark Edens, Brooks Wachtel, Steven Melching, and Len Uhley. A number of group had also worked on various Fox Kids shows anyway.
* PromotedFanboy: Writers/story editors Eric and Julie Lewald were fans of the other shows in the franchise, so they were thrilled to "write Hercules and Iolaus as kids."
* RealLifeWritesThePlot: One of the big rules was that Hercules could never meet Zeus in this series. When production knew they weren't going to be renewed for a second season, producer Cynthia Hsiung suggested doing just that for the last episode. Her bosses rejected that idea, but she managed to convince them to okay a story where Zeus met Hercules while in a mortal disguise.
* TheOtherDarrin:
** Ian Boen played Young Herc in the pilot movie and on ''HTLJ''. As Boen opted not to continue, Ryan Gosling took over for the series.
** There was also Sharon Tyrell, who played Herc's mother, Alcmene, in the series. In the pilot movie, she was played by Rachel Blakely. In ''HTLJ'', Alcmene as a young woman was played by Kim Michalis.
** Anthony Ray Parker played Bacchus in one episode of ''Xena: Warrior Princess'', but Kevin Smith (Ares himself) played him on this show.
* TroubledProduction: Slightly. The bonus feature on the DVD alludes to writers being dropped at the last minute and their replacements having to just jump right in. Also, due to the production schedule, the story editors had to juggle 15 to 20 episode scripts at once.
* WhatCouldHaveBeen: There were discussions of doing a spin-off about Kora.
* WritingByTheSeatOfYourPants: According to Brooks Wachtel, the earliest episodes were written before the staff had seen video of the New Zealand-based actors' work. He said they had to take a leap of faith in regards to how the characters would sound and behave.
* YouLookFamiliar: Michael "Iolaus" Hurst appears as a peddler in the pilot movie. He also returns in "A Lady in Hades" to reprise the role of Charon.
