- Actor-Inspired Element: Ben Affleck 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 Michael Bay.
- Adored by the Network: This movie seems to be on American TV every other day. Ranging from channels such as AMC and USA Network to MTV and the Lifetime Network.
- Backed by the Pentagon: 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 Mission Control room does appear in the film. Also the Pentagon.
- Breakaway Pop Hit: Aerosmith's "I Don't Want To Miss A Thing", their first ever #1 hit.
- California Doubling: 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.
- Creator's Apathy:
I asked Michael 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.
- According to Ben Affleck on the DVD commentary:
- 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.
- The Danza: William Fichtner as Colonel William "Willy" Sharp.
- Dueling Movies: This one was the winner vs. Deep Impact, at least financially. Primarily because where Deep Impact "tries" to be "inspirational", Armageddon knows it's 10% I Want My Jet Pack/90% Hollywood Science and just runs with it.
- DVD Commentary: A rather amusing one, wherein Ben Affleck spends a good portion of the time riffing on and making fun of his own movie.
- Executive Meddling: 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 Titanic (1997) with teenage girls. Most of the romantic scenes were written by Scott Rosenberg and were filmed late in production.
- Fake Russian: Peter Stormare, from Sweden, portrayed the loony cosmonaut. Of course, considering it's Peter Stormare, whose characters often steal the whole damn movie despite having limited roles, said loony cosmonaut is one of the best characters in the movie.
- Money, Dear Boy:
- The reason why why Billy Bob Thornton 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, Steve Buscemi 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.
- Old Shame:
- 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.
- Ben Affleck seems to get red in the face anytime its brought up, such as on Real Time with Bill Maher.
- Relationship Voice Actor: In the Mexican Spanish dub, Harry and AJ are also Super Saiyans (Goku and Vegeta, respectively).
- Shoot the Money: Pay attention to the number of, sometimes gratuitous, shots of helicopters. They were getting the most out of those rentals.
- Throw It In!: Michael Clarke Duncan improvised the line, "Come and get Papa Bear!" This later became one of his nicknames.
- What Could Have Been:
- Arnold Schwarzenegger 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 The Rock (a decision he later regretted).
- Milla Jovovich, Denise Richards, and Robin Wright were all considered for the role of Grace.
- Céline Dion was originally asked to sing and record "I Don't Wanna Miss A Thing" but passed on it, leading to Aerosmith to record and sing it instead.
