While by no means a classic, this slow-moving, but atmospheric Spanish/Italian co-production from director Jorge Grau (of LET SLEEPING CORPSES LIE fame) is at least a well-made and mature attempt at gothic horror.
Lucia Bose (very good, considering the uneven English-language dubbing) stars as the legendary "Blood Countess" Erszebet Bathory, who killed "610 Nubile Virgins!" and bathed in their blood to stay eternally young... and to impress handsome nobleman Karl Zimmer (Espartaco Santoni), who seems more interested in bedding the innkeeper's daughter Marina (Ewa Aulin) than anything else. Zimmer eventually helps out the countess by seducing women, slitting their throats and letting the blood leak out through a hole to fill a bathtub downstairs. Of course, the townspeople eventually catch on, and the bad Countess finds herself in a Edgar Allan Poe-ish situation at the conclusion.
I'd be lying if I said the film didn't lose me from time to time (American pre-released cutting may be the culprit), but it is still fairly interesting, has an authentic period setting (good sets, costumes, great-looking castles, lots of fog, etc) and is a bit more restrained (the most graphic gore is a scene when falcons eat another bird, which was probably real and not faked) than I expected. Worth a look, but I would give the Hammer film COUNTESS DRACULA (1970) with Ingrid Pitt the slight upper hand as far as Liz Bathory movies go.
Score: 5 out of 10
