* HilariousInHindsight: Stella questions how Thorwald, would've killed his wife. "Of course, the bathtub! It's the only place he could've washed the blood!" What other Hitchcock film was released six years after ''Rear Window''? ''Film/{{Psycho}}''.
* JustHereForGodzilla: To see [[TheCameo Ross Bagdasarian (Sr.)]] aka [[Franchise/AlvinAndTheChipmunks David 'Dave' Seville]].
* NightmareFuel: [[spoiler:Thorwald's off-screen murdering of his wife and how he apparently chopped her body parts into individual pieces. There's a brief implication that the item he had stored in his hatbox was her head.]]
* SpecialEffectFailure: [[spoiler: Jeff falling out of the window looks unmistakably like a chroma key effect.]]
** Plus, when everyone runs out into the courtyard to see this, it seems pretty obvious that they filmed the scene at normal speed and sped it up in post.
