* CrowningMusicOfAwesome: There is a reason that the soundtrack album was certified 15x platinum.
** How awesome was the soundtrack? Music/AliceCooper remembers panning the album to fans and the public, but privately, thought it was (and still ''is'') the best album he's ever listened to.
* JerkassWoobie: Even Tony deserves a little sympathy for all the crap he has to put up with.
* JustHereForGodzilla: Most of the people who saw the film in TheSeventies cared only for The Bee Gees songs and Travolta's dance numbers.
* MemeticMutation: In possibly one of the strangest crossbred memes in Internet history, this film plays a major part in a ''VideoGame/{{Touhou}}'' meme: Travolta's pose from the poster is extremely similar to the pose taken by Nagae Iku when she declares a spellcard, and fans did the rest. The meme is so prolific that Danbooru, usually dedicated to anime, manga, and video games, has tags for ''Saturday Night Fever'' and John Travolta.
* UnfortunateImplications: It's implied that the rape was LaserGuidedKarma for Annette trying for a RelationshipUpgrade with Tony and for getting drunk and high and trying to make him jealous. Coldly {{Lampshaded}} by Tony afterwards.
* TheWoobie: Poor, poor Annette.
** Bobby C., too. Tony is the only one who treats him vaguely like a human being.
