The Abominable Dr. Phibes (Robert Fuest, 1971)
Sublimely ridiculous Vincent Price horror movie, with Price as the titular doctor, who speaks through a hole in his neck and designs insane, baroque death traps to exact revenge on a group of doctors whom he blames for his wife's death. There are probably a million other Price movies I should see first, but a friend recommended this so I figured I'd give it a whirl and I was not disappointed. It's full of surprisingly sly humor, awesomely over-the-top set design, and Price acting his ass off without even moving his lips. How can you beat that?
