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.
Chapter 11 - S2-E3
Trivia: The idea of "mental contamination" mentioned at the start of the episode is real, and the demonstration using cheerleaders is based on fact. 5 cheerleaders and 5 other students had seizures in a town in 2002, in 1952 165 cheerleaders fainted before half time at a football game. A famous incident was in Le Roy in 2011 - those who were featured in the press took longer to recover than those who didn't, suggesting a strong social/communication basis.
Trivia: The voice of Onizuka in the English dub of the series is provided by Steve Blum. However, he had to use an alias ("David Lucas") due to the show being a non-union job. Blum has since jokingly denied that he and Lucas are the same person, despite it being a well-known fact that they are.
Trivia: Tyler Hoechlin, who plays Clark Kent, is only 14 years older than Jordan Elsass, who plays his son Jonathan Kent.
Trivia: When a Stormtrooper falls down into the mining pit after being shot by Ezra Bridger's energy slingshot, he yells the Wilhelm scream.
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: Ashley Johnson plays Anna Williams, the mother of Ellie. Johnson voiced Ellie in the video game the show is based on.
Trivia: Lieutenant Decker is the same Decker from The A-Team TV show.
Trivia: The planet that the Riker family settles on is called Nepenthe. A magical potion mentioned in Edgar Allen Poe's "The Raven," originally from "The Odyssey," with the power to cure grief and sorrow. A fitting name for a place to try to forget the loss of a child.
Trivia: This show pays many homages to the 1968 film Bullitt which was also set in San Francisco. Firstly officer Rebecca Madsen's car is the exact same make, colour, and model Mustang that Steve McQueen drove in Bullitt. Also the final episode (Tommy Madsen) features a car chase which recreates many shots from the 1968 film. It even includes the green Beetle Volkswagen coming down the hill as seen in the movie.
Trivia: Elise's parents, Don and Elise Sr. Are played by Michael Gross and Meredith Baxter. Gross and Baxter played husband and wife in the TV show "Family Ties" where Meredith Baxter played a character named Elyse.
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.
