- Adaptation Displacement: The movie is actually based on a book of the same name.
- It goes even further because many people only know of the Billy Idol song and have no idea it's based on this movie.
- Uncanny Valley: Christiane's mask, while extremely well-made and pretty, is creepy.
- Vindicated by History: Initial critical reception of the film was very negative, but nowadays it is placed along the best that horror genre can offer.
- Visual Effects of Awesome: The make-up effects still hold up wonderfully half a century later. Special mention to Christiane's face.
- The Woobie: Christiane.
