YMMV: Forbidden Planet

Forbidden Planet provides examples of:

  • Accidental Innuendo: "Pardon me, miss. I was giving myself an oil job."
  • Alternate Character Interpretation: Did the tiger come after Altaira because she felt sexual desire, or had it in fact been sent after the captain to assassinate him?
  • Ensemble Darkhorse: Robby, who went on to sci-fi fame.
  • Hilarious in Hindsight: Robby's voice actor would later team up with Leslie Nielsen again in a quite different project, as the announcer for Police Squad!.
  • Retroactive Recognition: Yes, that is, in fact, a young Leslie Nielsen, in his most famous "serious" role (and only his second-ever movie appearance).
  • Prop Recycling: Robby's prop ended up in several TV shows. As did the C57D, primarily on The Twilight Zone. However, from the late 1960s onward Robby's appearances were usually made by replicas, which weren't as heavy as the original.
  • Science Marches On: Altair appears as a spherical, reddish star in the film when it was well known to be a whitish A7 subgiant. In the 1960s, astronomers found it to be egg-shaped due to its rapid rotation.
    • The opening narration is actually fairly pessimistic about space exploration; it states mankind would not reach the Moon until the 2090s (over a century later than we actually did), and that reaching the rest of the solar system would be completed by the end of the 22nd century (we're still waiting on that one, but a lot of older sci-fi assumes we'll get there faster than that).
  • Seinfeld Is Unfunny: This was the science fiction film to watch until the release of Star Wars A New Hope and 2001: A Space Odyssey almost two decades later, and it reached this standard by having production values, story and scale greater than any film of the genre before it. It was stated by Gene Roddenberry to be one of his main inspirations behind Star Trek: The Original Series and is responsible for creating and/or popularizing most of the sci-fi tropes that we know and love. Today however it is most likely known as that film that looks like Star Trek, has a funny robot and features Leslie Neilson before he was funny.
  • Strangled by the Red String: Altaira goes from hating the Captain to deep, unbreakable love for him for no reason whatsoever.
  • Tear Jerker:
    • Jerry's death, horrific? Very much so...
    • Poor Doc Osgrow sacrificing himself to help everyone.
    • When Morbius finally comes to accept that it's his id monster that's been killing people (and is about to kill his daughter).
    • Morbius's death after banishing the id monster.
  • Values Dissonance: The film has a very 1950s view of gender politics, most notably in Adams blaming Altaira for all his men lusting after her just for standing around.
  • Visual Effects of Awesome: The monster, when visible, remains unforgettable to this day.
    • Try watching this film on a plasma, the backdrops are amazing!
