Five days ago, House of Evil replaced The Invisible Menace as Boris Karloff's worst film. Today, House of Evil was just replaced by Fear Chamber(viewings of The Snake People and The Invisible Invasion are pending as of now, hoping they are a little better). The only halfway decent thing about Fear Chamber is Boris Karloff, he doesn't have a lot to work with but he still delivers with conviction and dignity which is more than the material deserved. The rest of the acting is atrocious, especially from Isela Vega and Yerye Beirute, the latter bringing unintentional humour to his part. The production values are amateurish, the photography really does look as though it was shot in a matter of days, the effects are slipshod and the sets look like the film was shot in a basement. The music is at best shrill, though a marginal improvement over the music for House of Evil, at least it isn't as annoying. The biggest failings are the script and story. The script often doesn't make sense and written and delivered in such a wooden, stilted way. The story is just as incoherent, laboriously paced and more uncomfortably weird than creepy or suspenseful(and there was me thinking The Incredibly Strange Creatures Who Stopped Living and Became Zombies was weird). All in all, love and have a lot of respect for Karloff but Fear Chamber was just awful. 1/10 Bethany Cox

With its rep as one of Karloff's worst, I expected something drab and stilted (like CAULDRON OF BLOOD, '67) so was surprised to find this quite colorful, albeit in a tacky way. While it lacks subtlety (and often coherence), the film delivers sufficient sleaze to please prurient drive-in dwellers.The haphazard script provides much to mock. Spellunking scientists discover and attempt to communicate with a tentacled, "intelligent" rock. That's all of the plot you need...it's raw gibberish. Amoral researchers stop just short of human sacrifice in their experiments, and place blind faith in primitive, printout-spitting computers. Rants from Roland, the diamond-obsessed comic relief, beg for MST3K skewering, and Karloff's scientific theories are the daffiest heard since mad docs roamed the Monogram lot.Most commenters cluck about "Poor Boris." Granted, he isn't tossed one morsel of decent dialogue, but he just phones his part in. (The young leads, on the other hand, are quite likable, even though their characters are not.) Upon his passing, rummagers of Karloff's effects discovered that his check for this flick was uncashed...perhaps he expected it to bounce.

If you like old and strange movies this is your movie.Boris Karloff commands a group of scientists who finds an monster into the volcano. Experiments are made to understand this monster who converts fear in feed, but the monster is a rock!! Very good(?)!

A truly horrible movie, with no production quality whatsoever and Boris is immensely wasted in a small role as a scientist who conveniently becomes bedridden before the movie kicks into sadistic gear. A live rock is found under a volcano and Boris and his assistants set up a fear chamber to terrorize young girls. They then take the blood of the girls to feed the rock. Boris gets stressed out, bows out for a while, and his assistants proceed without him, kidnapping girls, whipping them, all sorts of sadistic merriment for fans of this stuff. There is even a strip tease for the rock! I can't say to avoid this movie, there are unintentionally hilarious moments, especially the character of Roland. But extreme fans of Boris will be shocked and outraged, to say the least.
