The article mentioned Brian Yuzna. Another good (if not extremely campy) movie he did was Necronomicon. In it, there is a scene where a guy is getting a blowjob from his dead wife, and tentacles come out of her mouth (including other orifices). That shit was disturbing. I tried to find an image but couldn't. I did find this one though, which is pretty spiffy. It's HP Lovecraft pulling a cultist's face off
