Dr. Marco (Ronald Remy) - a bald, acne-scarred vampire wearing Bono shades - tries to resurrect his dead girlfriend Katrina (Amalia Fuentes), but to do this he needs the heart of her twin sister Charito (also Fuentes). Charito's love interest Victor (Eddie Fernandez) tries to stop the bloodsucker from stealing his woman's heart - literally!
I can't totally hate on a horror film that features a rubber bat with glowing eyes, a hairy-faced hunchback AND an evil dwarf, but The Blood Drinkers is not a good film. Advertised as 'the first color horror picture produced in the Philippines', this is a cheap, shoddily assembled piece of schlock that doesn't even make good on its claim: SOME of the film was shot in colour, but much of it is merely black and white with a colour tint added in post.
The story plods, the acting is terrible (well, the dubbing at least), and Gerardo de Leon's direction is sloppy, the whole thing being somewhat confusing and incredibly cheesy at times (particularly the overuse of a smoke machine to try an add an eerie atmosphere). The worst scene, or the best depending on your point of view, is a fight between Victor and Marco's henchmen (the hunchback and the dwarf), with the little fellow delivering some particularly ineffective punches and being repeatedly thrown to the ground. Sadly, the bulk of the film isn't as funny and proved quite tedious.
3.5/10, generously rounded up to 4 for IMDb.
N. B. Aspiring suitors should never underestimate the aphrodisiacal effect of a water buffalo when serenading a young woman.
