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: In 2014, the series creators and network were sued for emotional distress by the family of a man named Andy Abarca. Abarca had been killed in a shooting, and actual photos from his autopsy were used in the opening credits montage of the show, evidently without any permission from his family. His mother and sister just happened to stumble across the show on one night in 2013 and were greeted with grisly images of their deceased relative. It was evidently allowed as autopsy photos are considered public documents. As of 2018, there have been no updates on the case.
Trivia: When Barry and Oliver are fighting on the street, a police officer asks for backup and mentions Burton and Nolan street, as reference to Christopher Nolan and Tim Burton.
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.
Clone Cadets - S3-E1
Trivia: Commander Colt watches Domino Squad do their test and says, "Start The Citadel challenge, version THX, variable 1138," which is a reference to THX 1138, another film by George Lucas.
No Magic at the Dinner Table! - S2-E3
Trivia: Paige Tamada, who played Elf Judy in "The Santa Clause" (1994), plays a street vendor in this episode.
Trivia: Poirot in the ship's lounge is reading the actual May 1st 1935 issue of Bystander (recognizable by the cover and with the correct page order, does not seem to be a simple movie prop), roughly consistent with the time frame of the first season and a contest taking place on the 14th. (00:07:50)
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.
Trivia: Jaleel White broke and permanently disfigured his right-hand pinky finger while filming this episode.
Trivia: Robert Patrick complains about the rise of the machines and asks who is that gonna be good for? This is an homage to his role in the Terminator 2 Movie as the T-1000.
Trivia: When Neil is being interviewed by Rebecca Halliday he mentions a fictional country named Equatorial Kundu. This is the same fictional country mentioned in several different episodes of The West Wing, also by Aaron Sorkin.
Trivia: Mike Pratt (playing Jeff Randall) really was laid up in a hospital bed with two broken legs. Mike Pratt was attempting to climb a drainpipe in a slightly inebriated state during his 38th birthday celebrations. He fell 20 feet into the basement area. He'd forgotten his keys, and saw the stand-in doing it - successfully - first. Mike being Mike, he thought, "I can do that" and had a go. Jeff's 'in character' excuse in the show was that he'd fallen from a balcony in a chase - a little more dignified than the truth.
Trivia: In the lift, Peter Scarborough mentions building 616. In Marvel comics, Earth-616 is the main dimension most of the stories are set.
