* ActorAllusion:
** Stanley Anderson played the President in Bay's earlier film ''Film/TheRock'', and the demeanor of both Presidents is highly similar.
** During his space dementia moment, Rockhound says "Yippie Kai Yo Kai yay" which is ''very'' close to the curse-free part of Creator/BruceWillis' Film/DieHard movies' CatchPhrase.
* ActorInspiredElement: Creator/BenAffleck came up with the idea for scenes of A.J. and Grace's wedding to be filmed on Super 8. His personal Super 8 camera was used for the shoot, and he held and operated it for all the shots he wasn't acting in. The cake fight was improvised, and the cast threw most of it at Creator/MichaelBay.
* BackedByThePentagon: NASA in this case. Hard to believe but it's true this did have NASA scientists as advisers and the movie was able to shoot in the NASA facilities. The only NASA place that isn't real is the control room which was designed for the film. Though the real MissionControl room does appear in the film. Also the Pentagon.
* BreakawayPopHit: Music/{{Aerosmith}}'s "I Don't Want To Miss A Thing", their first ever #1 hit.
* CaliforniaDoubling: The New York City scenes at the beginning were actually filmed in the Spring Street Financial District of Los Angeles. They actually manage to cover this up seamlessly for the most part, except for one shot of a guy in his car where you can see palm trees in the background.
* CreatorsApathy:
** According to Creator/BenAffleck on the DVD commentary:
--> I asked Creator/{{Michael|Bay}} why it was easier to train oil drillers to become astronauts than it was to train astronauts to become oil drillers and he told me to shut to the fuck up. So, that was the end of that talk.
** Regarding the line of "they don't know jack about drilling":
---> I mean, this is a little bit of a logic stretch, let's face it. "They don't know jack about drilling"? How hard can it be? Aim the drill at the ground and turn it on.
* DuelingMovies: This one was the winner vs. ''Film/DeepImpact'', at least financially. Primarily because where ''Deep Impact'' "[[TookTheBadFilmSeriously tries]]" to be "inspirational", Armageddon ''[[{{Troperiffic}} knows]]'' it's 10% IWantMyJetPack/90% HollywoodScience and [[HamAndCheese just runs with it]].
* ExecutiveMeddling: The original script did not include the romantic subplot between A.J. and Grace, and instead had more emphasis on Truman. It was added after the success of ''Film/Titanic1997'' with teenage girls. Most of the romantic scenes were written by Scott Rosenberg and were filmed late in production.
* FakeRussian: Creator/PeterStormare, from Sweden, portrayed the loony cosmonaut. Of course, considering it's Peter Stormare, [[OneSceneWonder whose characters often steal the whole damn movie despite having limited roles]], said loony cosmonaut is one of the best characters in the movie.
* MathematiciansAnswer: In some markets, this film was advertised as starring "Oscar winners Creator/BenAffleck and Creator/BillyBobThornton". While it is true that both these men won Oscars, neither of them won for acting.
* MoneyDearBoy:
** The reason why why Creator/BillyBobThornton was in this movie, which he wasn't shy to admit as soon as his contractual obligation to advertise the movie ended. He did say, however, that he didn't think it was that bad of a movie.
** When asked why he did the film, Creator/SteveBuscemi replied, "I wanted a bigger house".
** Lawrence Tierney repeatedly turned down the part of Harry's father, until he was offered a substantial pay raise.
* OldShame:
** Subverted. In an interview with ''Miami Herald'', Michael Bay said "I will apologize for ''Armageddon''", and explained how being forced to film the whole movie in 16 weeks caused the crew's performance to suffer, but later added on his website's forum that his words had been taken out of context and he actually was proud of the movie.
** Creator/BenAffleck seems to get red in the face anytime its brought up, such as on ''Real Time with Bill Maher''.
* RelationshipVoiceActor: In the Mexican Spanish dub, [[Creator/MarioCastaneda Harry]] and [[Creator/ReneGarcia AJ]] are also [[Anime/DragonBallZ Super Saiyans (Goku and Vegeta, respectively)]].
* ThrowItIn: Creator/MichaelClarkeDuncan improvised the line, "Come and get Papa Bear!" This later became one of his nicknames.
* WhatCouldHaveBeen:
** Creator/ArnoldSchwarzenegger was considered for the role of Harry. This is the second consecutive Bay directed film in which Schwarzenegger was offered one of the lead roles but turned it down, with the other being ''Film/TheRock'' (a decision he later regretted).
** Creator/MillaJovovich, Creator/DeniseRichards, and Creator/RobinWright were all considered for the role of Grace.
