* CreatorBacklash: After ''Film/ManOfSteel'' came out Bryan Singer commented on both that movie and this one. He is proud of what he made, but has expressed understanding of why audiences weren't as enthusiastic about it. In retrospect, he would have increased the action quotient or sped up the pacing (putting the airplane catch earlier in the movie), or else done a complete reboot. Beforehand, other people involved with the production expressed similar sentiments.
* DawsonCasting: Inverted. In spite of this film taking place five years after ''Film/SupermanII'', a 22 year old Kate Bosworth plays LoisLane. Made all the more noticeable when the five foot five actress is playing opposite six foot three Brandon Routh, who was only 25 himself when he was cast yet supposedly he is playing a Superman who is well over 30 and already a legendary figure in his own time.
* DeletedScene: The intended opening scene, of Superman surveying the remains of Krypton in his Kryptonian spacecraft, was completely cut out. It can be seen in its entirety [[http://www.youtube.com/watch?v=sF44PEypDQs here]].
** The scene also returned in the novelization.
* DyeingForYourArt: Brandon Routh had to work out, and blonde Kate Bosworth dyed her hair to become the brunette Lois Lane. KevinSpacey also shaved his head for SelfDemonstrating/LexLuthor.
* FranchiseKiller: If only because the sequel for ''Returns'' languished in DevelopmentHell.
* SavedFromDevelopmentHell[=/=]SequelGap: The fifth ''Franchise/{{Superman}}'' movie took 19 years, with many, many projects for a fifth Superman emerging since 1987 (another Cannon film, a film directed by Creator/TimBurton and starring Creator/NicolasCage, a film written by Creator/KevinSmith, etc).
* StuntCasting: The film homages the television show ''TheAdventuresOfSuperman'' with the casting of Noel Neill (Lois) and Jack Larson (Jimmy) in significant roles.
* UnderAgeCasting: Lois Lane is played by Kate Bosworth, who was only 23 years old and looked it. She was supposed to be an experienced reporter with a Pulitzer or two under her belt, not to mention a kindergarten-age son. Brandon Routh (Clark Kent) was 26 during production. The most problematic part of all this is that the movie is supposed to take place five years after the events of ''Superman 2'', which makes these characters 35 at the very minimum.
* WhatCouldHaveBeen:
** The final casting for the role came down to Brandon Routh and Creator/HenryCavill. Cavill was in fact cast in 2004 when it was going to be a full reboot, before [=McG=] was fired and Singer was brought in and made it not a reboot, and chose Routh for his closer resemblance to Christopher Reeve. Cavill was later cast in the role by Creator/ZackSnyder in 2013's ''Film/ManOfSteel'', which was a reboot.
** Creator/JimCaviezel expressed great interest in the role of Superman but Singer refused to cast the then 36 year old actor, even though he had the right look and the age of a more mature Superman, simply because Singer thought he was "too famous" after the controversial ''The Passion of the Christ'' - ironic considering that Singer tried really hard to pass Superman off as a Christ figure and Caviezel had just played Jesus Christ himself.
** During the initial fallout of the film's theatrical run Singer kept insisting in interviews that he would follow up with a more action packed sequel, he even likened his intended sequel to ''Film/StarTrekIITheWrathofKhan'' repeatedly (specifically saying that now that he had the set up he would go "all Wrath of Khan on it.") But due to the polarizing audience response and a lot of debate over the film's box office the sequel ultimately got scrapped in favor of what eventually became the 2013 ''Man of Steel'' reboot.
