* SugarWiki/AwesomeMusic: And this is, fellow tropers, how you compose epic score for a movie. Mark Snow's expanding on the theme and the varying main titles sound divine.
* FandomBerserkButton: For a while, ''calling this movie "TheXFilesFightTheFuture!"'' "Fight the Future" was originally a slogan, placed where a subtitle would go and thus mistaken for one. Some people could get really bent out of shape if you did this, but (1) it really did look like a subtitle, (2) the movie's gotta be called ''something,'' and (3) "I Want To Believe" really is [[TheXFilesIWantToBelieve the next movie's]] subtitle and it's in the same place in the logo as the words "Fight the Future" were on the first. By now, it's officially a subtitle; even ThePowersThatBe finally conceded.
* {{Narm}}: The immortal line "We will take that with which he cannot live without." Don't think about it too hard.
* OneSceneWonder: Armin Mueller-Stahl's brief performance as [[TheBigBad Conrad Strughold]], international head of the Syndicate, was well-received by fans. But the character never reappeared, nor was mentioned again.
* {{Shipping}}: So close! Damn you, you stupid bee!
