!! For the original TV series:
* BigNameFan: Creator/AynRand. [[NotMakingThisUpDisclaimer No, seriously]].
* TheCastShowoff: Before joining the series, Cheryl Ladd was already known as a singer (she was one of the singing voices in ''Series/JosieAndThePussycats'' and recorded an album with the group), and she used her fame on ''Charlie's Angels'' to launch a solo singing career that actually scored a few hits in the late 1970s. Not surprisingly, the series built an episode titled "Angels in the Wings" around Kris performing in a musical, allowing Ladd to sing several tunes.
* UnintentionalPeriodPiece: The fact that the series often took place in fashionable or modern settings makes it positively scream 1970's today.
* WhatCouldHaveBeen:
** Reportedly it was Creator/AynRand's favorite show and Farrah Fawcett was her top choice for the role of Dagny Taggart if ''Literature/AtlasShrugged'' was ever turned into a movie.[[note]]Unfortunately the movie version arrived two years after Miss Fawcett passed away.[[/note]]
** Kate Jackson originally signed on to play Kelly, being the first name the showrunners had in mind. However, when she warmed up to the role of the rather brainy Sabrina, the producers cast Jaclyn Smith as Kelly instead. This is why the pilot episode mainly focuses on Kelly.
** At the end of the fifth season, Jaclyn Smith’s five year contract was up, and she had made it clear she was not going to return. Interestingly enough, her character apparently was going to be killed off. But when the show was cancelled instead of renewed, it was decided that Kelly should remain alive for the sake of syndication. Had there been a sixth season of Charlie’s Angels, Kelly would have died.

!! For the 2000 Film series:
* ActorAllusion: When Dylan uses a flamethrower in ''Full Throttle'', the song "[[TheProdigy Firestarter]]" plays, as a reference to Drew Barrymore's role in the film ''Film/{{Firestarter}}''.
** In the first film, the house in which the two kids are playing a videogame when a naked Dylan comes knocking is the same house from ''Film/ETTheExtraTerrestrial''.
** Jason (played by Matt [=LeBlanc=]) is an actor and a bit of a ditz. [[Series/{{Friends}} Sound familiar]]?
** Creator/BruceWillis plays the first federal agent [[spoiler:Madison Lee (Creator/DemiMoore)]] kills. Guess that divorce wasn't as amicable as they made it seem...
* HeyItsThatGuy: [[Series/{{Friends}} Matt [=LeBlanc=]]] is Jason, [[Film/Terminator2JudgmentDay Robert Patrick]] is Ray Carter, a young [[Film/{{Transformers}} Shia LeBouf]] is Max, and [[Film/BackToTheFuture Crispin Glover]] is the Thin Man.
* RetroactiveRecognition: Melissa [=McCarthy=] as Doris, the Red Star receptionist.

!! For the reboot TV series:
* FakeAmerican: Rachel Taylor as an American since she's an Australian.
* ThePeteBest or TheOtherMarty: Robert Wagner was set to be the voice of Charlie (replacing the late John Forsythe) but was prevented by scheduling conflicts; ultimately Victor Garber supplied Charlie's voice.
