Return of the Wolf Man 1957

A thief (who is also a wolf man) breaks into Dracula's castle. He encounters a skeleton, and removes a stake from the bones. The removal of the stake revives Dracula, who bites Talbot the thief. Dracula then uses an electronic device to summon the Frankenstein Monster. The Monster leaves the castle. Talbot asks Dracula to cure him of his lycanthropy, but then transforms into the Wolfman. When the Monster returns, he and the Wolfman fight. The Wolfman transforms back into his human form, and then shoots the Monster and rams a stake back into Dracula's heart.
