John Carradine

I thought it was one of the best ever vampire performances ever, although he played a more menacing vampire in Billy the Kid vs Dracula

I have come to appreciate his take on Dracula in this and House of Frankenstein. While not as good as Lugosi (and let's face the fact that Lugosi wouldn't have been that different with the lack of screentime), I do enjoy his performance. Then again they seem to more say he's the book version of Dracula in House of Frankenstein since they say he was killed in Transylvania and in Lugosi's movie he was killed in England.
