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: They pay homage to the original 1932 movie Freaks. In Freaks, Cleopatra gets mutilated and turned into a tarred and feathered bird for visitors to gawk at in terror. Hercules gets viciously attacked under the carnival vehicle. In this episode, Stanley gets cornered by all the freaks under the carnival vehicle and gets viciously attacked and mutilated to resemble Meep (a feathered freak who was killed by the cops in an earlier episode).
Lion's Den - S7-E18
Trivia: After the race, Brae refers to Morris as "Flash." John Wesley Shipp, who plays Coach Shotwell and Morris' dad, starred as The Flash in the 90's TV show.
Blood Vessel - S1-E2
Trivia: The secretive room on the ship with a dark secret is cabin no. 9. Mark Gatiss, co-writer of this series, also co-wrote another creepy BBC series called "Inside No. 9"
Trivia: Originally, the new "Ghost Face" mask was meant to be made out of human flesh that was being stretched over the killer's face, hence it distorts and resembles a "screaming face" like the original Ghost Face mask. This idea was dropped relatively early in filming. However, several scenes had already been filmed with the killer for the pilot, so in some shots, the mask is actually a CG model that's been added in over the original. (Though thankfully it's hard to tell which scenes have the digital mask).
Trivia: Almost all of the rock songs in the soundtrack (which are primarily songs Ash listens to on the radio) are from the 1970's and 1980's. This was done on purpose, to help illustrate how Ash has been stuck in a state of emotional arrested development since his original adventures - he hasn't really grown as a person since.
Not All Men - S1-E7
Trivia: When Taissa leaves work and sees an angry man in his car repeatedly trying to jam his straw into his drink, the logo on the cup is the Busy Bee Cafe logo. The Busy Bee cafe was seen in the original Twilight Zone episode Nick of Time with William Shatner.
Model Kid/Public Television of the Dead - S2-E1
Trivia: When Kevin opens the fridge to get a bottle of beer, there's a milk carton in the back of the fridge. This carton has Laddie's picture on it from The Lost Boys, same as it was in that film.
Trivia: They used real wolves (no CGI) to play opposite Bill Compton in the last scene of this episode.
Trivia: The season five episode "Independence Day" featured Chris Bruno's brother Dylan. The episode itself was Chris' first time as a director.
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.
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 character of Dani Clayton is named after Jack Clayton, who directed "The Innocents." "The Innocents" is the film adaptation of the stage version of Henry James' "The Turn of the Screw." (Source: ScreenRant).
Trivia: At the beginning of this episode, after the Crypt Keeper causes the mirror to break, he mentions that he just bought seven years of bad luck. This show lasted for seven years.
Trivia: As Frank is running up the stairs in the FBI, just before he meets Peter you can see "Mulder and Scully" walking down the stair case - this is in fact David Duchovny and Gillian Anderson's stand-ins, but they do look a lot like them.
Trivia: At the comic book store, when Eric and Abby are talking, there is a "Plants vs Zombie" comic on the rack in front of them.
Trivia: Shooting scenes with Salem proved pretty difficult for Kiernan Shipka, who discovered on set that she's actually allergic to cats.
