_The Vampires' Night Orgy_ sounds like it should be a sleazy, European horror film, but it is nothing of the sort. There is one blink-and-you'll-miss-it moment of nudity, other than that this is just a throwaway vampire movie. Nothing is good here: the acting, the lighting, the dialog, all bad. There is no blood. The horror elements don't add up: we have one true vampire, and a town of people who act more like zombies - sorry, having bad teeth does not make you a vampire - a disappearing boy, and some cannibalism by proxy.
Do you want a plot summary? Here you go: people go to a small village, vampire, the survivors leave. There, you've watched the whole movie.
The reason I watched this was for Helga Line, but she is unrecognizable as the Countess, she's only in two scenes, and has maybe one line of dialog.
I can't recommend this to anyone, it's just absolute garbage.
