YMMV: Invasion of the Body Snatchers

  • Adaptation Displacement: The number of people who've seen the movies dwarf the number who've read the book quite handily.
  • Alternate Character Interpretation: Try watching Pleasantville immediately before or after the 1956 version; it's a weird antithesis.
    • Also, there's some room for uncertainty regarding whether the aliens are truly replacing the originals, and taking their memories is merely useful for blending in, or if they actually see themselves as merging with the original individual in a symbiotic relationship. This can make the aliens either a case of Always Chaotic Evil, or simply Blue and Orange Morality.
  • Crowning Music of Awesome: Danny Zeitlin's score to the 1978 version, helping enhance the horror through atonal, synthsizer-based jazz music.
  • "Funny Aneurysm" Moment: There's a moment early on in the 1978 film at a playground where a priest (likely having become a pod person) is on a swing while staring at small children who are playing. Suprised 4Chan hasn't picked up on that yet.
    • The priest, incidentally, is played by Robert Duvall in a cameo.
  • Hilarious in Hindsight: The pod people in the 1978 film would like to remind you that the yellow zone is for loading and unloading only.
  • Memetic Mutation: That "pointing" bit from the end of the 1978 film has become an Image Macro. No text needed.
  • Narm: Some of Miles's narration in the 1956 version crosses over into this, as does the whole OTT "You're next!" scene.
    "I'd been afraid a lot of times in my life, but I didn't know the real meaning of fear until... until I kissed Becky."
    • At least some of the horror generated by the infamous man-dog scene from the 1978 version is undermined by the banjo music playing in the background.
    • The pod scream in the 1993 version quickly becomes this, especially how the camera simply lingers on the pod person with no angles or quick cuts.
  • Nightmare Retardant: The 2007 version, which is Lighter and Softer than the previous versions and is Anvilicious in its attempts to incorporate The War on Terror.
  • Paranoia Fuel: Have your friends and loved ones been acting strangely lately? How strangely? By the way, if you fall asleep you might be replaced by an alien doppelganger. FYI.
  • Retroactive Recognition: That suspicious meter-reader in the original film? He's played by Sam Peckinpah, who later directed such films as The Wild Bunch and Straw Dogs.
  • Special Effect Failure: The man-mask on the dog in the 1978 version. In the long shots, it's a pretty obvious mask.
    • As the heroes escape in the 1993 version by helicopter, a pod person tries to sneak away with them, but is thrown out in mid-air. What follows is some pretty painful blue-screen effects.
  • Uncanny Valley
    • In universe as well, at least in the original. The duplicates look like, sound like, act like and have all the memories of the original, but their close relatives know something is wrong.
  • What Do You Mean, It's Not Political?: The original. The star and the director repeatedly insisted that they were all just making a sci-fi movie, not a social commentary.
    • Averted by the 1978 and 2007 versions, which were pretty heavily political, but surprisingly not the case with the '90s adaptation.
