Trivia: Stan Lee has a cameo in this episode as the man having his shoes polished next to Stark and Jarvis.
Trivia: The animated series featured the first appearance of the Holodeck (called the Rec Room) in this episode only. Gene Roddenberry wanted to use the Rec Room/Holodeck idea in the original live action series of the 1960s, but found that budgetary constraints were prohibitive at that time. The Rec Room finally appeared once in the animated series, in this episode, in 1973. It wouldn't be seen again until Star Trek: The Next Generation, in 1987, some 14 years later.
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.
Trivia: "Calcutta Adventure" is the episode where Hadji and Jonny meet and become friends after Hadji saves Dr. Quest's life from an assassination attempt.
Trivia: The news on the cell phone seen by Danny is written by Keira Morrisette - she is a co producer of the show.
Trivia: Though it serves as a "reboot" to the prior film series and is thus not related, Cary-Hiroyuki Tagawa reprised his role as the villainous Shang Tsung from the 1995 film due to the popularity of his portrayal of the character.
Trivia: In the lift, Peter Scarborough mentions building 616. In Marvel comics, Earth-616 is the main dimension most of the stories are set.
Trivia: Alan Ritchson, who plays Hawk, also played Aquaman in the Smallville TV 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.
Trivia: At approximately 29 minutes in, Ernie Hudson says "Who ya gonna call?" He is one of the original Ghostbusters from the 1984 film and this was the popular tag line in that movie.
Kiseki no fukkatsu! Yuyo no cosmo - S1-E5
Trivia: When Seiya opens his eyes hearing Miho calling his name, behind her in the audience a particularly bored animator decided to put in some silly characters, including the Tin Man, the Lion and a girl with the look of Dorothy from the wizard of Oz. (00:19:20)
Trivia: When Colt and Howie are performing the car stunt at the beginning, the footage used is from the 1976 film Cannonball.
Behold the Negative Zone - S1-E12
Trivia: When Blastaar comes through the Negative Zone into the Earth dimension, Thing remarks that Blastaar makes him look like Brian Austin Green. Brian Austin Green was the voice of Human Torch for the first season of this show. (00:11:18)
Trivia: Kingpin is voiced by Michael Clarke Duncan, who also played him in the live-action 2003 "Daredevil" movie.
Trivia: This series was roughly halfway through filming its 18 planned episodes when Marvel suddenly scrapped it and decided to start over and have just 9 episodes and hire a showrunner (a first for a Marvel Disney+ series). Reportedly, the original writing had a very legal procedural format, and Matt Murdock didn't even suit up as Daredevil until the 4th episode. In the process of revamping the series, Marvel decided to officially make the original Netflix show canon to the Marvel Cinematic Universe.
