* DawsonCasting: Largely averted for the main cast. One notable exception was Julie Condra, who guest-starred as a high school freshman at age 20. This made the story arc where Condra's obviously older, sexually mature character comes on to innocent young Kevin Arnold rather jarring.
* FakeAmerican: Olivia d'Abo (who was originally from the Paddington area of UsefulNotes/{{London}}). You know, Karen Arnold. Wait... you did remember that Kevin and Wayne have an older sister, didn't you?
* GermansLoveDavidHasselhoff: The series was pretty popular in Mexico during its broadcasting tenure, to the grade many of their voice actors had become celebrities (especially Kevin's younger and adult versions and Winnie's Mexican voice actors).

* KeepCirculatingTheTapes: Was this for a long time, due to the large amount of hit songs featured in the show, and the corresponding legal ''and'' financial snags involved with licensing the rights to all of that music.. Netflix and Amazon eventually secured streaming rights, but these still have edits to the soundtrack that include soundalikes and even an alternate version of the theme. In October 2014, Time Life/[=StarVista=] Entertainment released the complete series with the vast majority of the licensed music intact, and individually-released seasons have followed.
* MissingEpisode: The first of the show's two clip shows is not available for viewing on Netflix.
* RealLifeRelative: Danica [=McKellar=]'s sister Crystal plays Kevin's vengeful ex-girlfriend Becky.
** Also, Fred Savage's own little brother Ben Savage played the "cupid" character on the Valentine's Day episode.
* RetroactiveRecognition:
** "Hey, it's The Doctor from ''Series/StarTrekVoyager'' as the asshole Gym teacher!"
** And Karen is married to Ross from ''Friends'', you do remember Karen don't you?
** And [[WesternAnimation/InvaderZim Dib!]]
** Seth Green plays a student in "Lunch Stories" and "Sex and Economics".
** [[SubvertedTrope Subverted]] with Music/MarilynManson. Despite the urban legend that he played Paul, the role actually belonged to Josh Saviano.
* RomanceOnTheSet: In the Mexican Spanish dub, adult Kevin and Winnie's voice actors were married.
