- Adaptation Displacement: The film is iconic while many viewers don't even know about the existence of the 1909 novel until they've already seen the film. The Broadway musical has displaced the film itself somewhat, though.
- Ending Aversion: Most fans aren't very fond of the ending where the Phantom is killed by an angry mob, which was added in very late. The intent seems to have been to avoid making him a Karma Houdini, but the result comes across as a bit cruel when it comes right after he lets Christine go—he already learned his lesson, so why kill him now? Even Lon Chaney wasn't big on it.
- First Installment Wins: When it comes to the Universal Phantom films, this is the one that everyone remembers.
- It Was His Sled: Everyone who has ever so much as Googled the film knows what the Phantom looks like, which makes it a bit hard to realize how shocking he would have been to a new audience.
- Signature Scene: Christine's shocking unmasking of the Phantom is one of the most famous scenes in all of silent film.
- Visual Effects of Awesome: Lon Chaney was known for his effort that he put on his makeup, and this film was no exception. To say nothing of his ability to emote so flawlessly underneath all that makeup and without the aid of sound.
