* AccidentalInnuendo: "When you come, use the back door."
* AwardSnub: It lost that year's Tony to ''TheMusicMan''.
* EarWorm: Many, like "Mambo" and "America".
** "Tonight". Big time.
** "MARIAAAAAAAAAAAAA."
* EnsembleDarkhorse: Both [[SpicyLatina Anita]] and Anybodys.
* ItWasHisSled: Tony dies.
** NotHisSled: Unlike [[Theatre/RomeoandJuliet Juliet]], Maria lives.
* MemeticMutation: A rare case of a memetic dance--the Jets snapping their fingers and leaping in the air.
* MisaimedFandom: The entire argument over which gang is more sympathetic. It compeltely spits in the face the theme that both sides are adding to the conflict.
* MoralEventHorizon: It's pretty hard to root for the Jets after [[NearRapeExperience they attempt to rape Anita.]]
** Of course, [[RealityEnsues the entire point]] is to ''[[MisaimedFandom not]]'' [[MisaimedFandom root for either side.]]
* {{Narm}}: The fact that Action in the film looks like Matt LeBlanc.
** Or the fact that "Baby John" doesn't look or sound that much younger than the other Jets.
** A lot of the slang used by the Jets is cringe-worthy.
%%* NewerThanTheyThink
* OneSceneWonder: The unnamed girl in the song "Somewhere".
** Also John Astin as the MC at the dance.
* SeinfeldIsUnfunny: It can seem horribly cliche nowadays -- not least because it's adapting ''Theater/RomeoAndJuliet'', which itself underwhelms many readers who find it trite, shallow, and immature.
* SomeAnvilsNeedToBeDropped: Maria's closing speech where she chews out everyone over [[spoiler:Tony's death]].
* UnfortunateImplications: The 2009 revival of the musical on Broadway had the Sharks singing and speaking in Spanish when among themselves -- which adds to the realism, right? Except... that the most popular number that the Sharks sing, "America," is still sung totally in English, and the song "Un Hombre Asi/A Boy Like That" starts out in Spanish when Anita is singing of her hatred and desire for vengeance, and then turns to English when Maria sings about love, forgiveness, and self-sacrifice.
* WhatDoYouMeanItsNotSymbolic: The virginal Maria wears a white dress to her first dance, but a red one following the loss of her virginity to Tony. Also, in the final scenes, she's wearing a black shawl around her head. Probably representing her mourning for her brother, but it comes in handy when she has to mourn Tony as well.
* WTHCastingAgency: For a part of a Puerto Rican in a musical, a Russian-American was cast, who couldn't sing (okay, NatalieWood actually could sing, but she wasn't good enough for this movie).
** Also compare white Carol Lawrence in the original Broadway cast (although she could sing).
