Review by gravelbreath

The US release of this film was called "The Black Pit of Dr M." and was brought to the US (along with several other great Mexican horror classics) from Mexico by B movie maven, K Gordon Murray. As far as I am concerned this film is one of the absolute treasures of Mexican Cinema. How often would you hear that about a Horror film? Fernando Mendez's great horror masterpiece is so rich in atmosphere and boasts such beautiful, Gothic "mise en scene" that it looks like a true Gothic fairy tale painting has been struck right on the screen. I've seen scores of classic horror films and I have yet to see one that matches the almost over-the-top lush style and atmosphere that Mendez has created here. The setting is an old Hacienda, shrouded in mist, filled with exotic plants and photographed with such care it is almost mesmerizing to see. This Hacienda is an insane asylum headed up by Dr. M. When a spirit conjurer is called in to resurrect the life of a man who was wrongly executed, vengeance, murder and mayhem from beyond the grave ensues. A wonderful, supernatural tale, told in a lyrical yet almost surreal fashion combined with unrelenting, spooky visuals makes this greatly under-appreciated film an absolute must see.
