YMMV / Plan 9 from Outer Space

  • Accidental Innuendo: The co-pilot asks the stewardess if she'd like to "ball it up" in Albuquerque. Even in The Fifties, "balling" meant something other than going to a dance ball.
  • Critical Research Failure: "A ray of light is made up of many atoms." As if this film didn't have enough snark bait, it's pretty much 7th grade knowledge that light is made out of photons, not atoms.
  • Cult Classic: Thanks to it's So Bad, It's Good nature.
  • Designated Hero: Jeff. Honestly, he could be considered the villain.
  • "Funny Aneurysm" Moment: Ed Wood's cameo as a drunken bum, which is pretty much what he would become in his later years.
  • Guilty Pleasures: Delightful when viewed as a G-rated comedy.
  • Inferred Holocaust: Plan 9 is to stop humanity building a "solaranite bomb" and destroying the universe. Yet Plan 9 fails. What does this mean for the universe? Given that it's the Plan 9 Universe, total destruction may be merciful.
  • Memetic Mutation: "Future events such as these will affect you in the future" and several other Department of Redundancy Department lines.
    • "You see? YOU SEE? Your stupid minds! Stupid! STUPID!"
    • Tor Johnson's damn blank-angry face when he becomes a zombie has achieved this status, even becoming a mask!
  • Older Than They Think: Criswell's opening line — "We are all interested in the future for that is where you and I are going to spend the rest of our lives" — is often held up as one of Wood's classically clunky lines. In actual fact, Criswell used that as the intro line for his TV show for several years before Plan 9 was filmed (and continued to do so afterward), though he usually gave it a much wryer delivery than he does in Plan 9witness it in action in his appearance on the Johnny Carson New Year's Special in 1966.
  • So Bad, It's Good, apparently enough to have an operating system named after it. And a video game, and a label company, and three bands, and some other stuff.
  • Special Effect Failure: The tombstones wobble when people hit them. Also, the flying saucers which are square when they land and are visibly suspended from strings.
  • Strawman Has a Point: If, and only if, such a device that could blow up not only the world but the universe were plausible - then these visiting aliens would have a good point in trying to prevent it from being built. They really need to work on their methods though...
  • Woolseyism: The fact that some subtitled and dubbed versions have better writing than the actual movie is less of a show of the translators' skills and more damning evidence of the movie's own ineptitude. Just being able to truncate the redundant dialogue and make some phrases sound much more natural is an improvement already.
