* BillingDisplacement: Creator/NancyAllen gets second billing (under Creator/RobertJohnBurke), despite having less screentime than Creator/RipTorn (who appears in more scenes than her), and despite being [[spoiler:killed off a third of the way through the film]].
* BoxOfficeBomb: Budget, $22 million. Box office, $10,696,210.
* CaliforniaDoubling: The film was shot in UsefulNotes/{{Atlanta}}, using many of the buildings that would soon be torn down to make room for the facilities for the 1996 Summer Olympics.
* CreatorBacklash:
** Creator/NancyAllen wasn't fond of the movie and didn't want to be part of the movie in the first place; she specifically requested that [[spoiler:her character be killed off]] in order to get out of the franchise.
** Edward Neumeier, co-writer of the first movie is also [[https://www.youtube.com/watch?v=Ehdg95fdR2g on record]] as to hating the weapon arm and jetpack.
** [[http://www.robocoparchive.com/archive/movie-robocop3-dekker.htm Fred Dekker voiced his opinion about the finished product]]. While he maintained that he had a great time making it and was still pleased with the result, he admitted that there were inherent problems with the film as well as limitations in its production. He felt that one of those problems was that Murphy/[=RoboCop=]'s personal journey had already been wrapped up in the first movie, leaving little more for him to do than fight bad guys in the sequels. His biggest regret was that he had toned down the action, cynicism and violence too much at the request of the studio, who wanted to direct the movie at a younger audience (since they had already produced the animated series). Also, the basic premise of [=RoboCop=] siding with homeless people against an evil company did not suit the political climate at the time. Lastly, he had intended to put in more Hong Kong-style action through the Otomo character (being a big fan of that genre), but he lacked the budget to hire an Asian stunt team that could pull it off. What haunts him to this day about making the film is the screenplay itself. He felt that if he had another writer who had written the script like Creator/FrankMiller or his best friend, Creator/ShaneBlack, he would've had a different perspective and strengthened the roles of the actors in the film. He also personally regrets not setting up the scene where [=RoboCop=]'s Flight Pack is introduced. If he had to do it over again, he would've showed what its capabilities were for the payoff at the end of the film. Dekker also said that he regretted [[spoiler: not resurrecting Lewis as a [=RoboCop=] herself, which he felt would have validated the movie's existence.]]
* CreatorKiller: After having some success directing the cult films ''Film/NightOfTheCreeps'' and ''Film/TheMonsterSquad'', Fred Dekker hasn't directed anything after the failure of this film. He would find some work as an uncredited script doctor for ''Film/DemolitionMan'' and ''Film/LethalWeapon4'', but he wouldn't receive another credit until being credited as a co-writer for ''Film/ThePredator'' in 2018, ''25 years'' after this film.
* DyeingForYourArt: Because Orion wouldn't put up the cash to build new suits for Creator/RobertJohnBurke, he had to wear a slightly modified version of the suits Creator/PeterWeller wore in ''Film/RoboCop2''. Burke had said wearing the suits, even for a short time, was painful due to the height difference between him and Weller.
* FranchiseKiller: The film was critically panned for its banal subject matter compared to the previous two installments and, when audiences took notice, flopped at the box office and single-handedly killed the franchise for over twenty-one years. Between that time, attempts to continue the popularity of the franchise through a live-action TV series, a second animated television series, a comic book series, a live-action miniseries and a video game from Titus Software didn't really help matters.
* KilledByRequest: As noted above, [[spoiler:Creator/NancyAllen specifically asked for Lewis to be killed off.]]
* TheOtherDarrin: Contrary to popular belief, Creator/PeterWeller was actually interested in returning for this film, and actually came to visit Fred Dekker personally. They spent a good half an hour talking together, in which he told him that he wanted to do it, but had a conflict with filming ''Film/NakedLunch'' in which he had been recently cast after actively campaigning for the lead role. Dekker was very impressed and honored to this day by the fact that Weller actually came over to talk to him about his intentions. The scene where [=RoboCop=] receives facial reconstruction after being badly damaged and burned was written in to explain why [=RoboCop=] no longer looked like Weller in his scenes without his helmet.
* PropRecycling: The "Johnny Rehab" action figure line that is shown in the third act of the film is notably the "Robocop and the Ultra Police" toys of the late Eighties.
* RefittedForSequel: Plot elements like OCP forcing people to move from their homes with Rehab-forces and the donut shop scene with all the cops pulling their guns out came from Creator/FrankMiller's [[ComicBook/FrankMillersRoboCop original script for]] ''Film/RoboCop2''.
* ReleaseDateChange: The film was originally scheduled for a summer 1993 release, but being a relatively low-budget action movie, it was pushed back to the fall of 1993 to avoid competition with expensive blockbusters like ''Film/JurassicPark1993''.
* TheShelfOfMovieLanguishment: The film completed production in 1991 and was initially scheduled for release in the summer of 1992. It would languish on the shelf until the following year as Creator/OrionPictures went through bankruptcy and was bought out.
* SparedByTheCut: [[spoiler:In addition to the Rehabs being recycled from original from Creator/FrankMiller's original script for ''2'', so was their plan to discredit Murphy by framing him for the murder of one of his fellow officers -- only in said script, it was [[BlackDudeDiesFirst Sgt. Reed]]. When it was revisited for this film, it was changed to Lewis and Reed survives the film. This also extends to several Metro West officers as the Rehabs also killed several of them in the climax of the script.]]
* ThrowItIn: As revealed in his Netflix special, ''Our Man in Chicago'', it was Creator/JeffGarlin's idea for his character, the doughnut shop clerk, to be eating a doughnut in the scene where the shop is nearly robbed -- and ended up sick because he ate 36 doughnuts over the course of filming.
* WhatCouldHaveBeen:
** As with the second film, Creator/FrankMiller was initially hired to write the script, and then his script was heavily rewritten. He later turned the unused script into a comic - ''ComicBook/FrankMillersRoboCop''.
** Originally Nikko was named "Keiko" and she was a four year old Japanese girl who was a genius. This explains why her mother was Japanese in the film and was later changed when the production could not find a young girl who could've played the role and reworked it to an American girl.
