Needs an Alice Cooper soundtrack. Referring to the OP's video. Could not reply or quote, because the software does not allow double posting of video's in a single post.
Captain Kronos Vampire Hunter (1974) One of my favorite Hammers (outside of Horror of Drac and Curse of Frank), and Hammer has the full movie for free on their youtube channel. It's not a traditional vampire movie, as there's no blood and fangs to speak of. But it's got a cool hero and his hunchback sidekick, as well as Caroline Munro.
Let's not forget about Vampira (and Ed Wood) vampire movies. Oh, and let's not forget Bella Lugosi's final swan song in Ed Wood's classic movie. Viva, Plan 9 from Outer Space!
I've been aware that I'm due to watch that again, both the original and remake. Oh I remember the twins alright. Not complete without Count Frightenstein!
Maltin was often an idiot. It has a wonderfully gothic atmosphere and has an unusual but compelling story for a vampire flick. Check the reviews over on Amazon to get a much better idea of its value.
