* ActorAllusion: Annie Potts's character answers the phone at the record store, "Tracks, what do you want?" similar to how she did in ''Film/{{Ghostbusters1984}}''.
* ActorInspiredElement: Jon Cryer suggested "Try a Little Tenderness" by Music/OtisRedding for his dance. His original suggestion was "State of Shock" by Music/MickJagger and Music/MichaelJackson, but the filmmakers couldn't get the rights.
* InMemoriam: The movie is dedicated to Alexa Kenin and Bruce Weintraub. Kenin, who played Jena, was murdered in New York just before the movie was released. Set decorator/production designer Weintraub died of AIDS at age 33.
* StarMakingRole: For Creator/JamesSpader.
* ThoseTwoActors: Creator/JamesSpader and Andrew McCarthy would work together the following year in ''Film/LessThanZero'' and ''Film/{{Mannequin}}''.
* ThrowItIn: When Duckie gets thrown into the girl's bathroom, he says regarding the tampon machine, "We don't have a candy machine in the boys' room". This was ad-libbed by Jon Cryer. He also ad-libbed the line, "His name is Blane? That's a major appliance, that's not a name".
* WhatCouldHaveBeen:
** Creator/JodieFoster turned down the role of Andie. Tatum O'Neal, Lori Loughlin, Diane Lane, Creator/SarahJessicaParker and Brooke Shields were also considered.
** Creator/AnjelicaHuston and Creator/TraceyUllman were both considered for Iona.
** In a podcast interview, Creator/MollyRingwald revealed that Jennifer Beals was set to replace her in the lead unless she didn't accept, but the director Howard Deutch eventually vetoed the idea.
** Anthony Michael Hall turned down the role of Duckie, as he didn't want to get typecast. He also felt that the film was rehashing ''Film/SixteenCandles''.
** Creator/CharlieSheen auditioned for Blane.
** Creator/RobertDowneyJr. was almost cast as Duckie when the ending had Andie getting together with Duckie. Per Creator/MollyRingwald, this ending may have stuck if Downey won the role because he didn't give her the "brother vibe" Jon Cryer did.
* WordOfGay: Both Creator/MollyRingwald and Creator/JonCryer have agreed that after high school, Duckie came out of the closet and is currently a HardGay, wearing no shirt and suspenders and attending Gay Pride events. Could be considered a mix of WordOfSaintPaul and WordOfDante, of course. Keep in mind, though, that Creator/JohnHughes originally wanted Andie and Duckie to end up together, so this is not really WordOfGod.
