* AllStarCast: Creator/TomCruise, Creator/JackNicholson, Creator/DemiMoore, Creator/KieferSutherland, Creator/KevinBacon, Creator/JTWalsh, and Creator/ChristopherGuest. Creator/KevinPollak, Creator/NoahWyle, and Creator/CubaGoodingJr don't really count since they weren't particularly well-known at the time, making them more a case of RetroactiveRecognition.
* BeamMeUpScotty: The famous quote said on this page is often interpreted as simply just one line: "You want the truth? You can't handle the truth!" This is mostly due to the fact that it's usually just one person making the reference where accurately quoting it takes two people.
* BreakthroughHit: Creator/AaronSorkin had had some success as a playwright, but was no household name. Adapting his play to the big screen opened the door to other movies and successful ventures in television.
* CastTheRunnerUp: Creator/KevinBacon originally wanted to play Jonathan Kendrick, but Creator/RobReiner thought it was a typical role for him. He wanted to give him a more challenging role and cast him as "Smiling" Jack Ross instead.
* CompletelyDifferentTitle: The film would be titled ''A Question of Honor'' for its international release in quite a few countries (''Cuestión de honor'' in Latin America, ''Et spørgsmål om ære'' in Denmark, ''Eine Frage der Ehre'' in Germany). Meanwhile in Sweden, its title was ''På heder och samvete'' (''By Honor and Conscience''). In Italy its title was ''Codice D'Onore'' (''Code Of Honor'').
* DescendedCreator: In the film, Harold Dawson was played by Creator/WolfgangBodison, who served as a film location scout during production.
* DuelingDubs:
** The movie has been dubbed in Korean for airing twice. One for KBS and the other for MBC.
** It has also been dubbed twice in Latin American Spanish. The original dub was made by Procineas S. C. L. in Mexico, while the redub was made by Palmera Record in Argentina.
* HideYourPregnancy: Creator/DemiMoore was eight months pregnant with her second child Scout Willis when she was cast, which is why Galloway is almost never seen out of her (clearly too large) uniform.
* IronyAsSheIsCast: Creator/TomCruise, whose StarMakingRole was in ''Film/TopGun'', and who is a licensed pilot in real life, playing Daniel Kaffee, who's afraid to fly because he gets sick on planes.
* TheOtherDarrin: Quite a few characters in the film are not played by the actors from the stage play.

* ThePeteBest: On stage, Roxanne Hart originated the role of Galloway during out-of-town tryouts and early on Broadway, only to soon be replaced with Megan Gallagher, [[https://www.nytimes.com/1990/11/09/theater/on-stage-and-off.html a highly publicized move]] as Gallagher was in a relationship with Creator/AaronSorkin at the time.
* PlayingAgainstType: J.T. Walsh was well known for playing slimy shady characters. Here he plays an upstanding, ethical (if spineless) military officer.
* ProductionPosse:
** This marked Josh Malina's second time working on something Creator/AaronSorkin wrote; he plays Tom, Jessep's secretary. Malina was first in the Broadway play this movie is based on, as an ensemble member and understudy, later getting promoted up to play private Downey.
** In addition, it also featured three creatives who previously worked on ''Film/{{Stand by Me}}''; its director (Rob Reiner), studio (Creator/ColumbiaPictures) and co-star (Kiefer Sutherland).
* RealLifeRelative:
** Aunt Ginny is played by Creator/RobReiner's sister-in-law, Maud Winchester.
** Kevin Pollak's mother Elaine Harlow is in the crowd watching the trial. According to Pollak, she hit on Creator/JackNicholson.
* SelfAdaptation: Creator/AaronSorkin wrote the film adaptation from his own stage play.
* ThrowItIn:
** The infamous "You can't handle the truth!" line was originally written as "You already have the truth!" Nicholson felt the character's hubris would be better communicated by revealing that he believes himself so intellectually superior to everyone else that no one but him could comprehend the reasoning behind his actions rather than simply attempting to skirt blame.
** Creator/TomCruise's Creator/JackNicholson impersonation (when his character is quoting Colonel Jessep) was not scripted. Creator/DemiMoore's and Kevin Pollak's reactions are genuine.
* UncreditedRole: Creator/WilliamGoldman did an uncredited re-write of the screenplay. Creator/AaronSorkin was so impressed by Goldman's new dialogue, as well as changes that tightened the story, that he re-wrote and re-published the play to incorporate the changes.
* WhatCouldHaveBeen:
** Creator/RobertDeNiro and Creator/RichardDreyfuss wanted to play Col. Jessep.
** Creator/JodieFoster, Creator/LindaHamilton, Creator/ElizabethPerkins, Creator/MichellePfeiffer, Creator/NancyTravis and Creator/JulieWarner were considered to play Galloway. However, Castle Rock wanted a tougher actress, so the role eventually went to Demi Moore.
** Creator/JasonAlexander was supposed to play Sam Weinberg, but when ''Series/{{Seinfeld}}'' was unexpectedly renewed, he was no longer available.
* WriteWhatYouKnow: Creator/AaronSorkin wrote the play after learning from his sister Deborah, who had recently joined the Judge Advocate General's Corps, that she was working on a case that inspired the events of the play.
* YouLookFamiliar: In the film, Jessep's clerk is played by Josh Malina, who previously appeared as an ensemble member in the original stage play.
