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: 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)
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: 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.
The Return of the Beast: Part 1 - S1-E1
Trivia: When we see the flashback of the accident that caused Bruce Banner to become the Hulk, at first we see the Hulk colored gray and then slowly turn green. This is a reference to the comics, in which the Hulk was gray in his original appearance.
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.
Trivia: The show is adapted from four of Gillian Cross' "Demon Headmaster" novels. The first half of the first series is adapted from "The Demon Headmaster", the second half is adapted from "The Prime Minister's Brain", the second series is adapted from "The Demon Headmaster Strikes Again" and the third series is adapted from "The Demon Headmaster Takes Over."
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 Tall Knight is played by Peter Mayhew, best known for portraying the Wookiee Chewbacca in the "Star Wars" movies.
