this film mark the end of the serious universal monster era ( abbott and costello meet up with the monster later in abbott and costello meet frankentstein ) . it be a somewhat desparate and yet fun attempt to revive the classic monster of the wolf man and frankenstein monster and and dracula one last time . i say desparate and because in the previous film and house of frankenstein and both dracula and the wolf man be kill accord to how the vampire and werewolf legend say they should be ( dracula by the sunlight and and the wolf man by a silver bullet ) . yet somehow they return in house of dracula with no explanation . this movie could have play a a kind of prequel to house of frankenstein if the frankenstein monster plot wouldn not be continue chronologically into house of dracula from house of frankenstein and and if the wolf man do not get cure . then there would be no plot hole . but since this be not the case and the plot of dracula and the wolf man make no sense . however and ignore these plot hole and house of dracula be a classic atmospheric horror film that fun to watch . it have many high point . especially see the wolf man get cure . i know i just say that this shouldn not have be include and but it be nice to actually see him get cure after all this time . and the scene with the lady play moonlight senada and on the piano then all of a sudden playing a haunting melody when under dracula spell be very eerie . dr. edleman transformation into the dr. jekyl or mr. hyde type character be also do very well . and it great to see dracula and frankenstein and and the wolf man together and one last time . out of .
