This movie is somewhat crude and tacky, yet it added a significant element of science fiction that tempered its trite monster/horror backstory. The bargain basement Dr. Frankenstein in this film sought a biochemical solution to tissue regeneration via a trauma-induced spike of adrenaline. There is a little bit of science fact in his pronouncements though like most science fiction the rest is rubbish.
I saw this film at least 30 years ago and I recall some scenes that differed from what is available now. The full-length film is easy to find on You Tube. In these uploads, Dracula (Zandor Vorkov - Roger Engel) wears a ring that gives him superpowers, the most memorable of which is the ability to emit a heat ray or lightning bolt that immolates the victim. In all of the videos I have seen, I saw Dracula use the ring that way only once. In the re-run I saw many years ago, he used the ring on several other victims and also verbally threatens to use it on other individuals to get them to comply with his demands. I vaguely recall an ending different to the classic decomposition of Dracula when he is exposed to sunlight. I am unsure about the ending but am certain that there were other scenes with Dracula employing his evil ray ring more than once. In fact I had written up a summary of my recollections of the story over a decade ago to send out by email for story ID. Any input is greatly appreciated.
