Trivia items for the comics:
- Actor Allusion: Rogue is stuck between three vampires, two wanting revenge and the other ordering them to let her go. "She killed Marv! She doesn't get to walk away from that... even if she is a dead ringer for the chick who plays Sookie."
- Fan Nickname: Madelyne Pryor has been called Maddie, Lynne, Queeny, and any number of other things by characters both in and out of universe.
- The Astonishing X-Men ongoing series took full four years to complete a 25-issue storyline. As a result, Shadowcat being Put on a Bus was spoiled by Messiah Complex: since its events couldn't take place before it, Kitty was nowhere in sight. The series is notoriously hard to fit into Marvel continuity, as it appears to take place over at most a few weeks, but the second arc is set prior to House of M (Xavier and Magneto are hanging out on the ruined Genosha) and the final arc includes a dialogue reference to Civil War having happened! The series was first written by Joss Whedon and then Warren Ellis continued the trend. The reason is the same.
- Un-Canceled: The original X-Men title was canceled after seven years of horrible sales and no popularity (it was revived nine months later, but only published reprints of earlier issues). It was basically seen as a poor-man's version of the Fantastic Four. Then it was rebooted with all new characters like Nightcrawler, Storm, and Colossus, along with minor Hulk villain Wolverine. Under the skilled writing of Chris Claremont, it became Marvel's flagship title throughout the '80s and '90s.
- What Could Have Been:
- Wolverine was originally going to be a wolverine who was mutated into a human.
- Claremont's original endgame for the Scott/Madelyn saga was for Scott to actually retire and settle down permanently.
- Madelyn Pryor was originally intended to be just as she appeared — a woman who looked exactly like Jean, but nothing more. However, when plans were started to resurrect Jean to reform the Original X-Men for the 25th anniversary of the title, a major problem presented itself — Scott and Maddy had married and were happy. That's when the Summers marriage fell apart. Hence the twist that she was a clone engineered by Mister Sinister, her becoming the Goblyn Queen and her death during Inferno.
- Sauron was originally supposed to be a vampire. Also, Claremont considered bringing him into the X-Men full-time as their resident doctor in the 1980s.
- The story with the X-Men facing Krakoa in Giant-Size X-Men #1 (May, 1975) is familiar. But it was only the second concept for the reintroduction of the team to readers. The original one was rejected. According to Dave Cockrum, the original story would feature figures from Aztec Mythology. "It was something to do with sending the new team down to South America to rescue the old X-Men and finding a whole bunch of Aztec gods walking around and raising hell and having to combat the Aztec gods who would wind up to be the original X-Men dressed as Aztec gods." Cockrum disliked the idea and convinced writer Len Wein to dismiss it and start working on another one.
- One early version of the story in Giant-Size X-Men #1 would have the original team be in no real danger. Instead of an actual mission, the entire dangerous situation would turn out to be an elaborate entrance exam. Testing potential X-Men for the proper skills to actually join the team. And there would be those who flunked the test and be rejected. The obvious candidates for Len Wein and Dave Cockrum were two already established characters: Banshee and Sunfire. Originally they were supposed to be the only ones. Then the creators decided to also have one of the new characters fail. Choosing Thunderbird, whose flaw of being anti-social would make him unsuitable. The duo of creators started having second thoughts about letting Banshee and Thunderbird go, which resulted in them scrapping the idea of the exam.
Trivia items for the animated series:
- Fake American: Most of the voice actors were Canadian. Professor Xavier's was English, which is especially amusing given how the film series would make the character himself English.
- The Other Darrin: A few voice actors are changed, most noticeably Gambit in the final season.
- Out of Order: Some episodes that were intended for season 4 were pushed up to the third season. In turn, some season 3 episodes were pushed back - most ridiculously the episode "No Mutant Is An Island" which is supposed to take place during Jean's death between the Phoenix Saga and the Dark Phoenix Saga.
- Postscript Season: Word of God states the "Beyond Good and Evil" four-parter was originally intended to be the Grand Finale. A renewal order led to a few more episodes being produced before the final end with "Graduation Day."
- What Could Have Been: Multiple X-Men attractions were proposed for Universal Orlando's Islands of Adventure park during its development phase in the early/mid 90's. The first one would've had guests venturing inside of the Cerebro chamber and witnessing a big battle between the X-Men and Magneto's forces. The attraction would have utilized a moving theater that would've been surrounded by a giant 3D dome screen. The second proposal, which almost made it into the park, would have been an interactive dark ride where guests would be able to shoot at targets and score points. This fell through due to the extreme budget cuts the park received as a result of The Amazing Adventures of Spider-Man and Jurassic Park River Adventure going heavily over-budget. The third and final proposal was a stunt show, which too ended up being a victim of further budget cuts. An X-Men ride did finally come to park in 2000, though in the form of a small teacup ride called Storm Force Accelatron.
