Rarely does the movie ever live up to the title in films of this era. The Torture Chamber Of Dr. Sadism's title doesn't either; as there is no one named Dr. Sadism, but there is a torture chamber at least. Here's the rundown. A dude named Count Regula killed 12 virgins so the townsfolk attached a golden spiky mask to his face and decides to tear him into four large chunks. Years later, invitations to the Count's castle somehow get delivered and two dummies travel to check it out. So then highwaymen attack their horse-drawn carriage on a foggy tree-lined road, crows sit in the gnarled limbs of trees where dozens of corpses dangle in atmospheric eerie blue half-darkness, and groovy psychedelic music with odd backwards effects plays. It's quite a sight.
I have a question, though, and it's one that has plagued movie-goers for like ever. If you've just risked your life fighting off hooded highwaymen on a tree-lined road littered with dangling corpses, and you finally arrive at your destination which is a crumbling ruin of a castle surrounded by a graveyard, and a crypt suddenly opens on its own revealing a subterranean passageway; would you go in? If so, why? Do you honestly think things are going to improve? I would have my doubts.
Anyway, there are secret passages, and snake flinging, and a hallway of vultures, and a hallway of skulls. That stuff is pretty good, but it doesn't make a lot of sense. Stuff just seems to happen. Then there are trapdoors, and bong-like laboratory equipment, and a sharp swinging pendulum, and someone uses hay as a pillow, and someone throws a vulture. It's a freaked out psychedelic mess.
Spoiler: Nothing says "Wow, we just escaped the clutches of Christopher Lee wielding a gigantic axe like the soothing tones of jazz flute.".
I watched The Torture Chamber Of Dr. Sadism on youtube, and it's highly recommended if you like stuff that sucks or if you just happen to be a little bit stoned. Here's a German trailer:
