'''''House of Dracula''''' is the last "serious" Universal MonsterMash film. It is from the year 1945.

After the events of ''Film/HouseOfFrankenstein'', the yet again revived WolfMan Larry Talbot is still seeking release from his condition. He ends up in Dr. Edelmann's place for treatment and accidentally finds FrankensteinsMonster in the caves under the house. Count {{Dracula}} is also there to find a cure for vampirism, but it is only a ruse to get near the nurse Morella, upon whom he has set his sights.

This film is also notable for having a female hunchback assistant, though she is treated as a sympathetic and kind character (and is quite pretty to boot).

Next up, comedy duo {{Abbott and Costello}} [[Film/AbbottAndCostelloMeetFrankenstein stumble upon the Monster Mash]].
!!Witness the tropes which pile the horror upon horror!

* BungledSuicide: Larry decides that one more transformation to a werewolf is too much and attempts to kill himself by leaping off a cliff. He survives and ends up in cave where the Monster is.
** Bit of FridgeLogic as well, because at this point in the series Larry should be well aware of how hard it is to kill him. Even a silver bullet only puts him down until some jackass exposes the corpse to moonlight.
* ContrivedCoincidence: The quicksand where the Monster drowned in ''House of Frankenstein'' conveniently leads to the underground caves of Dr. Edelmann's place.
* TheCorruption: Courtesy of the blood of {{Dracula}}, Doctor Edelman is changed from [[JekyllandHyde a noble, devout, and compassionate scientist into a mad killer]].
* DoingInTheWizard
* EvilDetectingDog: Dr. Edelmann's cat.
* ForScience: When finding the Monster, Dr. Edelmann attempts to power up the Monster. Nina talks him out of it, reminding him that the Monster is too dangerous to be revived.
* GlamourFailure: Dracula casts no reflection to a mirror, nor does the evilized Dr. Edelmann.
* HopeSpot: Out of five movies, this is the only one that ends well for poor LawrenceTalbot (yes, by Talbot standards being forced to shoot the man who cured your nightmarish curse to prevent him from suffering the same fate constitutes ending well). He's cured, and he has a love interest. By the sequel though, he's relapsed, and she's nowhere to be found. Probably dead.
* HospitalHottie: And in truly subversive and original twist, one of them is TheIgor! Okay, well, technically, she's Dr. Edelmann's hunchbacked original assistant. But she's still a rather lovely and compassionate woman.
* MadScientist: Dr. Edelmann's evil side.
* NightmareDreams
* ThePowerOfBlood: Dracula's blood can apparently turn normal people completely amoral.
* ScreamingWoman
* TalkingToThemself: Well, it's more a case of ''Arguing With Himself In A Nightmare'', but after [[TheCorruption he gets nailed]] with Dracula's blood, Doctor Niemann has a dream in which his good and evil selves quarrel over the idea of turning the FrankensteinsMonster loose on the villagers.
* TorchesAndPitchforks
* TortureCellar: An old one is under the Edelmann's house.
* TransformationSequence
* UnexplainedRecovery: No attempt is made to explain how Dracula and Talbot survived their onscreen deaths in ''Film/HouseOfFrankenstein''.
** Earlier movies establish that Talbot revives when his corpse is exposed to moonlight. Whoever found his body after the last film probably didn't know that.
