!! The 1994 cartoon:
* HeyItsThatVoice: [[JohnRhysDavies Sallah]] is Thor.
** [[Creator/TonyJay Megabyte]] is Galactus.
** [[VideoGame/MetalGearSolid3 The Boss]] is Sue Storm
** The first Torch is [[TheSarahConnorChronicles Kyle Reese]], while the second one is [[VideoGame/MetalGearSolid2 Raiden]]
* TheOtherDarrin: A coupleómost notably, Doctor Doom and the Human Torchóbut nowhere near as extreme as what ''WesternAnimation/IronMan'' went through.
** ''Three'' people actually voiced Doctor Doom during the series' run.
* WhatCouldHaveBeen: Plans for a third season included Sue's pregnancy (with She-Hulk or Medusa filling up the vacancy) and the return of the Sub-Mariner.
** And probably we've seen the return of Puppet Master, and find out where he's been.

!! The comic book:
* WhatCouldHaveBeen: According to Stan Lee's [[http://goodcomics.comicbookresources.com/wp-content/uploads/2009/08/synopsis1.jpg initial]] [[http://goodcomics.comicbookresources.com/wp-content/uploads/2009/08/synopsis2.jpg plot]], published in ''Fantastic Four #358'', Sue was originally permanently invisible, and she'd be more or less an InvisibleStreaker.
* During Creator/ChrisClaremont's run on the title, he had initially planned for [[Comicbook/XMen Kitty Pryde]] to be a recurring cast member, serving as a live-in nanny for Franklin Richards (this took place shortly after ''Comicbook/{{Excalibur}}'' was cancelled). Then-editor of the X-Men franchise Bob Harras wanted Kitty back in the main X-Men team.

!!The films:
* ActorAllusion: More "actor input", actually: Julian [=McMahon=], who plays Dr Doom, suggested that metal staples be used to help stitch the scar at the beginning of his transformation. This comes from [=McMahon's=] experience playing a cosmetic surgeon on ''NipTuck''.
* CreatorBacklash: JessicaAlba said she absolutely hated working on the Fantastic Four sequel, so much that [[CreatorBreakdown it almost made her quit acting altogether.]]
** ChrisEvans wasn't so crazy about working on the film either.
* DoingItForTheArt: One of Chiklis' requirements for accepting the role of the Thing was that his character would be make-up based, rather than the CGI everyone else had previously assumed. This meant that Chiklis insisted upon hours of application and wearing heavy, uncomfortable makeup, over the option that would have allowed him to earn the same money in significantly less time simply by voice acting. Why? Because Chiklis was a fan who knew that underneath the rock skin, Ben Grimm's still a human being, and this was best shown by having his actor go through the same thing.
* FakeAmerican: Welsh Creator/IoanGruffudd as Reed.
* FranchiseKiller: The ''Silver Surfer'' spinoff isn't going to happen.
* HeyItsThatGuy:
** [[Creator/AndreBraugher Frank]] from ''Series/HomicideLifeOnTheStreet'' is a General now?
** [[Creator/IoanGruffudd Harold Lowe]] not only survived Film/{{Titanic}}'s incident, he also survived cosmic rays exposure and becomes Mr. Fantastic.
* MeaningfulReleaseDate: It was originally supposed to be released on July 4, 2005, and early trailers played this up. However, its release date was shifted to four days later.
* PromotedFanboy: Michael Chiklis has been a comic book fan since he was a kid. [[CaptainObvious Guess which one was his favorite.]]
* ThrowItIn: "Aw, look -- she's kissing him."
** It may have also been for the benefit of Alicia, who was standing right next to him,(she's blind).
* WhatCouldHaveBeen: The 2005 film was originally meant to be, in executive producer Chris Columbus' words, "the most epic sitcom ever made", and they were consciously ''trying'' to duplicate the formula that had resulted in the utter failure of ''Film/BatmanAndRobin'' -- Columbus' reasoning being that while ''Batman'' wasn't an appropriate franchise to attempt such a formula, ''The Fantastic Four'' was. After a few years in DevelopmentHell, the arrival of Tim Story (who, ironically, was mostly known as a comedy director) and writer Mark Frost finally pushed the film in the right direction.
** This feel is best seen in the hilarious breakfast scene and the montage that follows it. The whole thing plays out like an hilarious cross of ''LeaveItToBeaver'' and ''Series/TheAddamsFamily''.
