Bloodlust!

I'd file this under "No classic, but lots of fun!". The cast is good: It's interesting to see Robert Reed in his pre-Brady Bunch days. The late Wilton Graff (as the villain) is one of those faces many remember but can't name; he was usually seen as concerned fathers or business execs who knew more than they were telling. He gives a convincingly understated performance in this film; one is constantly reminded of Vincent Price. Plotwise, there are some effective jolts along the way (bodies floating in tanks, or posed in realistic attitudes in a "trophy room"). There's also a memorable scene where a young lady karate-flips a would-be attacker into a vat of acid; we're offered screaming closeups of his skin peeling away. The lively finale involves quicksand, leeches and a body hung (still living) on a spiked frame. Like I said, no classic, but if you enjoy the occasional anything-goes exploitation film, you could do worse!
