Fiend is Like Friend Without the 'R' - S1-E4
Trivia: Nergal is the villain introduced in this episode. "Nergal" originally was the name of the Babylonian God of Fire and Guardian of the Underworld. In the Bible, he is one of the demons allied with Satan himself. In the series Nergal is associated with the underworld and fire.
Trivia: They used real wolves (no CGI) to play opposite Bill Compton in the last scene of this episode.
Trivia: There are a lot of Greek references. Cerberus, Tartarus, a messengers boots (Hermes reference) and the princesses. Twilight is the Greek word for friend love, or Philia. Cadence is Eros, or romantic love. Celestia is Agape, the love God has for mankind. Well, Celestia is kind of a god. Luna is Storge, love of a mother and child. This works because she has helped Scootaloo and Sweetie Belle in a motherly way. She was a mentor to both of them.
Trivia: The season five episode "Independence Day" featured Chris Bruno's brother Dylan. The episode itself was Chris' first time as a director.
Trivia: When Barry is checking the results of his tests in the police lab, he turns to the computer to view the screen. The camera changes to see the screen, and for just a moment (just a few frames) we see what was on the screen before his results - a couple of stolen car reports, one of which is that of "Joliet Jake Blues" (from the Blues Brothers movie). And yes, the car and licence are the same as in the movie. I don't know what the connection is; I assume someone on the crew loved that movie. (01:12:00)
Trivia: Its teaser trailers are, for the most part, out-take footage that doesn't actually appear in the episodes. For example, in the scene in which ShadowMoon and Mr. Wednesday first meet aboard the airliner, the teaser trailer uses completely different camera shots and different performances from the actors. In the actual episode, the camera shots and performances for the same scene are noticeably different.
Trivia: A sequel to the original film, titled "The Power of the Dark Crystal," was initially planned. However, the film spent many years in development hell with several different writers and directors being attached at different points. Eventually, French director Louis Letterier became attached to the project around 2012, and it was subsequently retooled into this prequel series for Netflix. "The Dark Crystal: Age of Resistance" was finally released in the Summer of 2019 - almost 37 years after the original debuted in Winter, 1982.
Through the Rabbit Hole - S2-E1
Trivia: The boy's comment, "Everybody is kung fu fighting" at the ruined school dance, refers to Carl Douglas' song of the same name from 1974, two years before this episode takes place, following the fledging martial arts craze in America. This song has recently (in a slight variation) resurfaced in Kung Fu Panda.
Trivia: **SPOILERS** When the demon takes over Ciri's body she dreams about being back at the party her grandmother had at their castle, and she sees her grandmother, Mousesack, her mother and her father. When she starts to question if it's really her grandmother, Mousesack and her mother all turn to ash and blow away. If you pay attention, you'll notice that her father does not turn to ash which is a foreshadow for later when it's revealed that he is in fact still alive.
Trivia: The music used for the Octopus Dare computer game is an 8-bit rendition of the show's main theme tune.
Trivia: When the Girardis are debating over what to watch for movie night, Will suggests one of the Godfather films. Joe Mantegna previously had a supporting role in The Godfather Part III.
The Scorn of the Star Sapphire! - S3-E5
Trivia: After freeing Miss Taylor from the grip of Star Sapphire, Green Lantern encases her in a green energy box and flies her away. The box is shaped almost exactly like a shuttle craft from Star Trek. (00:15:50)
Trivia: After modeling in underwear in an issue of Maxim magazine to promote "Drive Me Crazy", Archie Comics threatened to sue Melissa Joan Hart for breach of contract and to fire her from the show, as her contract stated she could never portray Sabrina naked, and the name "Sabrina" was printed on the cover of the magazine. Hart was able to make the situation go away simply by writing an apology letter.
The Trial of Audrey Parker - S1-E11
Trivia: When Audrey is looking for a secret compartment in the bookcase, you can see a copy of "The Tommyknockers." This is a Stephen King novel that's set in the town of Haven.
Trivia: The song playing on the radio when Rosebud breaks in, 'I'd Take a Bite of the Moon For You,' references the episodes 'Alone Together' and 'Tick Vs. Chairface Chippendale.' The song playing when El Seed breaks into the botanical gardens is a jazzy version of the show's theme song.
