The fourth film adaptation of ''ThePhantomOfTheOpera'' (and the second one by Universal), released in the year 1943.
Paris Opera House violinist Erique Claudin (Creator/ClaudeRains) finds himself out of a job due to his deteriorating playing skills, which proves to be a problem as he needs the money to pay for the singing lessons for Christine Dubois (Susanna Foster), a rising young talent in the opera, whom he is obsessed over. He tries to have his concerto published in order to fix his money problems, but due to [[DramaticIrony a tragic mistake]], he ends up disfigured and on the run from the law. He then takes refuge in the underground tunnels of the Opera House, and sets out to help Christine in her career, no matter how many corpses must he leave behind.
Surprisingly, in place of the more famous 1925 Phantom of the Opera, THIS Version, the 1943 Version, is one of the eight Major Universal Monsters!
!!This film has the examples of:
* AbsurdlySpaciousSewer: Claudin gets away from the chantarms by escaping through the sewers of Paris.
* AdaptationalAttractiveness: Comes with the territory.
* AllThereInTheManual: It's never stated, but Claudin is in fact Christine's DisappearedDad (hence the transferral of the third member of the LoveTriangle to Anatole). Universal decided to cut all references to this lest it add accidental IncestSubtext for viewers who remembered the setup in the 1925 film.
* AnonymousBenefactor: Claudin was one for Christine, as he paid for her singing studies.
* CanonForeigner: Anatole.
* CareerVersusMan: The film ends with the LoveTriangle [[DumpThemAll unresolved]], and with an implication that Christine chooses to pursue her career instead.
* ChekhovsGun: The acid in Pleyel's office.
* CoatHatMask: Claudin's disguise as The Phantom.
* DramaticIrony: When Erique Claudin tries to have his work published, one of the publishers tells him that he never received it. Little did either of them know, was that the company was showing Erique's work to renowned music critic FranzLiszt to get his testimonial for its publication. When Erique hears his music being played to Liszt in the other room, he assumes that the company stole his music and [[FreakOut strangles the publisher to death]]. The publisher's wife then grabs a tray of etching acid and... well, you know the rest.
* DramaticUnmask: As Christine sings for Claudin in the climax, she gets closer to him until she can rip off his mask and reveal his burned face to the audience.
* FacialHorror: Claudin getting splashed with acid.
* FallingChandelierOfDoom: When Claudin's demands of letting Christine sing are not met, he drops the chandelier on the unsuspecting audience.
* GorgeousPeriodDress: Prevalent in the opera performances.
* HighClassGlass: Worn by Lecours.
* HistoricalDomainCharacter: FranzLiszt.
* LostInImitation: This version changed the nature of the Phantom's ugliness from deformity to disfigurement, and several subsequent adaptations followed suit.
* LoveTriangle: Differing from the usual setup, it's not Raoul and The Phantom competing over Christine, but Raoul and a fellow opera singer named Anatole.
* PublicDomainSoundtrack: The performances depicted in the film were based on works in the public domain.
* RunningGag: Raoul and Anatole trying to fit themselves through the same doorframe.
* TheScrooge: As Claudin has secretly spend all his money on Christine's education, his landlady thinks that his overdue rent is caused by him being a miser and complains him about it.
* StandardFemaleGrabArea: Claudin manages to drag Christine all the way down to his underground lair against her will by grabbing her arm with one hand.
* TamperingWithFoodAndDrink: Claudin tampers with Biancarolli's drink to make her unable to sing.
* ToTheTuneOf: Claudin bases his concerto around the Provencean lullaby he (and Christine) knows.
