Curiouser & Curiouser - S2-E22
Trivia: All the sets in the dream sequence, particularly Nick's loft, are filled with props referencing Lewis Carroll's Alice in Wonderland books. They include white rabbits, flamingos, walruses, a squeaky-toy caterpillar - even a half-eaten piece of cake in Nick's fridge. The episode also has several background extras in Wonderland-style costumes, and numerous other references to the books, such as Nick literally falling through the looking glass at the end.
Trivia: The episode revolves around a man killing people with the same first names as the thirteen apostles (Mary Magdalene being the 13th), and killing them in a similar fashion in which the apostles died. At one point, Colby and David find a box with a mannequin's head in it. This is a reference to the film Se7en, in which seven people are killed for committing one of the seven deadly sins. The film ends with the main characters finding an actual head in a box.
Trivia: As the detectives are trying to find out from Doug Hutchinson's character where the victim is being held, the detectives find out he is somewhat claustrophobic. They decide to scare him and put him in a cupboard without any light. This is very similar to Doug Hutchinson's character in The Green Mile. The main characters decide to punish him and force him into a dark and small room.
Trivia: In "Four dreams" the alternative Allison who doesn't have children looks at some kids in a restaurant and gets a dreamy look on her face. The mother of the children she is admiring addresses her daughter as "Sofia". The "real" Allison's daughter Ariel is played by actress Sofia Vassilieva.
Trivia: Peter Billingsley of "A Christmas Story" plays Gideon in this episode. This was his television debut at age 11.
Trivia: Here and in several other episodes, Burke's Law was one of the first TV series to break with longstanding Hollywood prejudices by hiring Latino actors like Cesar Romero to play Latino roles. In this episode, three years before becoming the Joker on Batman, Romero plays a Mexican police chief interrogating Amos Burke, whose rather prescient line to him is, "The joke's on the joker - I've been framed!" (00:06:30)
Trivia: The first time Chris Noth had played Mike Logan since Exiled: A Law & Order Movie.
Regard a Mere Mad Rager - S2-E19
Trivia: Even though simply opening the door is the solution, the math problem given yields an imaginary number. In the problem "boing" equals -1 and "flarp" equals 2. Then it asks what is the square root of -1 over 2. It's impossible to get the square root of a negative number since any number times itself yields a positive number.
Trivia: Michael Mann was originally against casting Don Johnson. Prior to this TV series, Johnson had starred in four failed TV pilots.
Trivia: In season 2, episode 2, Jude dyes her red hair blonde. In actual fact, Alexz Johnson, who plays Jude, is naturally blonde.
Trivia: Sam mentioned an old case from 1999. In the German dubbed version, it's from 1990 (even in the German subtitles it's 1999). Obviously the missing nine years takes to long to fit into the mouth movements. (00:11:10)
Trivia: In the movie, a soldier called Petronius unsuccessfully tries to murder the emperor Valentinian. The name "Petronius" was probably chosen because in reality the emperor was eventually killed by a senator called Petronius.
All-New Halloween Spooktacular! - S1-E6
Trivia: When Pietro says he'll help the twins maximise their candy acquisition, one twin says "Kick-ass!" and Wanda repeats to herself "kick-ass." Both Aaron Taylor-Johnson, who played Pietro in Avengers: Age of Ultron, and Evan Peters, who plays "Pietro" in WandaVision and the recent X-Men films, both starred in Kick-Ass.
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: Although they played father and son in this episode, Jack Elam was only six years older than Harry Dean Stanton.
Trivia: Anna Walton, who plays Diane de Poitiers, is only 3 years older than Torrance Coombs, who plays her son Sebastian.
Trivia: The call sign for the mobile command center is SHIELD 616. Earth-616 is the name for the primary universe in Marvel comics.
Trivia: While Hank and Dawn are in the warehouse on the truck there is the name "Ditko Movers", a reference to Steve Ditko, the creator of Hawk and Dove.
I Was a Middle Aged Werewolf - S4-E5
Trivia: When Mark is in the motel room watching TV, the movie he is watching is "I Was A Teenage Werewolf", starring a young Michael Landon, star of this show.
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.
