House of Dracula (1945)
Dracula and Larry Talbot are both seeking a cure for their respective monster afflictions from a brilliant scientist, Dr. Edelmann (Onslow Stevens).
Dracula actually appears to be searching for a cure for his vampirism. (Somehow Dracula has survived his destruction by sunlight exposure in the previous film, House of Frankenstein) and initially seeks to be cured of his vampirism at the hands of the doctor, as Dracula has apparently tired of his vampiric nature. But after re-meeting the doctor's beautiful assistant, whom he knew in his alias of "Baron Latos", Dracula's evil nature reasserts itself, and he infects Edelmann through a blood transfusion of his vampire blood, which turns Edelmann into a Jekyll and Hyde like creature. Though Edelmann succeeds in destroying Dracula, Edelmann realizes that he is slowly degrading into a murderous monster himself.
Lawrence Talbot soon arrives at Edelmann's castle, seeking a cure for the curse that turns him into a werewolf (As with Dracula, his return from destruction dealt at the end of the previous entry is not explained, but his recuperative ability via moonlight has already been established in the earlier Frankenstein Meets the Wolf Man). The Frankenstein Monster plays a minor role in this film, only being found during Talbot's attempt at suicide by drowning in the ocean late in the film. The Monster does not actually go into action until almost the climactic finish, which results in Talbot finally being cured of his affliction and falling in love with Edelmann's attractive assistant, Miliza Morrelle (Martha O'Driscoll) and killing the Hyde like version of Edelmann. The Frankenstein Monster is burned to death in yet another fire, resulting in the destruction of the castle he is in.
