That is one of my most favorite adaptations of Stoker's Dracula. Here's an interesting trivia tidbit. In America, the Hammer classic had the title "The Horror of Dracula", but in England, where it was made, it had the simple title of "Dracula". That had to do with copyright laws, as the Stoker family still retains the rights to the title. For some reason, "Dracula" could be used in England, but not in America. That's why the Coppola version was called "Bram Stoker's Dracula". Once again, it woud've violated copyright law to just call it "Dracula". I think, but I'm not sure, that the reason why Lugosi's "Dracula" was able to get away with it was because Universal technically did a filmed version of the stage play (which had permission to use the title), not the novel (the same with the Frank Langella version).
