Trivia: The show is based on a comic books series written by Gerard Way, who was the lead singer for the band My Chemical Romance.
Trivia: Simon Pegg's extended cameo as Hughie's father is a specific nod to the comics - the look of "Wee Hughie" in the original comics was based on Simon Pegg. Artist Darick Robertson said "it was important to capture an innocence but tough determination in Hughie. Two things that seemed to contradict each other and somehow in early sketches he kept looking too old. When I saw Simon Pegg in Spaced I thought he captured that balance perfectly." Pegg knew he was too old to play the character himself, but was happy to play his father.
Trivia: Will Keene, who plays Father McPhail, is the real-life father of Dafne Keene, who plays Lyra Belacqua, the main protagonist in the series.

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: 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.
Crisis on Infinite Earths: Part Two - S1-E9
Trivia: The version of Batman played by famous Bat-voice Kevin Conroy is a darker version of that from the graphic novel The Dark Knight Returns. The line "the world only makes sense when you force it to" is a version of a line from that comic (also used in Batman V Superman), also "Clark always said yes to anything with a badge or a flag." There are also elements from Batman Beyond, which first aired in 1999 (hence Earth-99), in which Conroy voiced an older Bruce Wayne mentoring a new Batman. The whole scene is full of nods to other versions - describing Kryptonite as "a little souvenir from the old hometown" is a Lex Luthor line from the original Superman movie, and him describing Superman as "strange visitor from another planet, with powers and abilities far beyond those of mortal men" comes from Superman serials from the 40s and 50s.
