The Vampires Night Orgy (1973)
Fairly obscure Spanish horror flick starring Jack Taylor (best known for his collaborations with Jess Franco) and Belgian Eurohottie Dyanik Zurakowska.
A coachload of workers on their way to start new positions in a Spanish town are forced to spend the night in a small village when their driver dies at the wheel. A village that doesn't appear on any map. Initially they find the place deserted and decide to make themselves comfortable for the night. The next day, however, the population returns. The travellers are made to feel welcome, but as time goes by they find more and more obstacles to their leaving. One-by-one they discover the truth about their hosts - they are all vampires!
It's a pretty standard 'travellers forced to stay in isolated place' plot. The acting is okay but not outstanding, and as with a lot of these Eurohorrors the music really doesn't fit with some scenes. However, the film's strength lies in the atmosphere it generates (despite the dodgy music!); it's very creepy and unsettling, and the vampire attacks (including one really nicely set-up in the disabled coach) are genuinely menacing.
Zurakowska is ably supported in the glamour stakes by Helga Liné and Charo Soriano, and there is nudity in the full-length version, although it's nowhere near the skinfest you might expect from the title. And, surprisingly, for a vampire film there's actually very little gore (when you consider Hammer had been splashing blood all over the screens for years and were very popular in Europe).
Worth a watch but not one I'll revisit any time soon. 5.5/10
