  • Alternate Character Interpretation: Has anyone noticed that the Prime Minister is literally see-through? Combined with the fact that he has less of his face covered than any other character, this may be because he's one of the top politicians in the land, and therefore needs to be transparent in the metaphorical sense for his people.
  • Cult Classic: Like Labyrinth before it.
  • Dawson Casting: The two main leads are supposed to be teenagers. Helen was played by 21 year old Stephanie Leonidas, and she played a believable 16-year-old. However, Valentine was played by 33 year old Jason Barry, and despite the portrayal, his age made him appear to be in his mid-twenties at earliest, making the sexual tension of the finale a bit uncomfortable for viewers.
  • Everyone Is Jesus in Purgatory: For real, this time. The whole thing is extremely psychological.
  • Fridge Horror: With a hint of Never Mess with Granny. The Sphinx are very heavily implied to be man-eating. Mrs. Bagwell has at least 30 of them in her house, if unwillingly. Her advice to Helena? "Don't let them see you're afraid." Bit of a Crowning Moment of Awesome for the old bird.
  • Hilarious in Hindsight: Stephen Fry delivering a voiceover about creating an imaginative fantasy world.
  • Nightmare Fuel:
    • "Why do birds / Suddenly appear?" with some intentional Uncanny Valley for good measure.
    • Note that the Uncanny Valley just topped it off, it wasn't by far the most disturbing part of the scene. The symbolism and literalism, especially with the Soundtrack Dissonance thrown in, was the most disturbing part of the scene.
    • "Hungry. Still hungry."
    • "And dear, don't let them see you're afraid."
    • The puppets in the below entry. There's just something about them that makes you wonder what's going on in their heads...
  • Toy Ship: Helena and Valentine have a bit of Ship Tease going, particularly when he shows up in the real world at the end. But since it's implied she's early-to-mid teens (though played by a 21-year-old actress) and he's late-teens-to-early-twenties, they might want to wait a few years.
  • Uncanny Valley:
    • The puppets in the "Close To You" brainwashing scene. What makes them uncanny is that though they are obviously unnatural clockwork, they have elegant motion-capture movements and perfect choreography. It's like watching wooden skeletons perform Swan Lake.
    • The sphinxes may also fall in here, though they're so goofy and cartoonish it blunts the effect.
    • There's something unsettling about just about everything in the movie from characters to creatures to sets. Eventually, your brain just adapts to it. Or doesn't. The above entries are just particularly notable instances since they still manage to be creepy and "off" in an entire movie set in the land of creepy and "off".
