Coventry H.P. Lovecraft's good name is shamelessly being violated in this ultra-embarrassing excuse for a horror movie. Supposedly based on the legendary novelist's writings, this movie handles about a group of retarded crooks home-jacking an elderly magician and his daughter. Too bad for the coke-addicted bunch the old man has severe issues himself, as he once sacrificed his own wife to the forces of witchcraft. For some reason (whether unexplained or I missed it) all evil suddenly is unleashed upon the mansion and everybody dies in cheesy ways! Believe the bad rating of this film because this really is the kind of garbage that gives the horror genre a bad name. We're talking atrocious acting, one-dimensional characters and abysmal dialogue. Although I'm sure the makers like to believe so, there's absolutely no suspense throughout the entire film and the forced implementation of occult elements (like the black cat, the altar and the Cthulhu-handbook) only makes it more ridiculous. The gore is a lot less outrageous as you would expect (seeing absolutely nothing happens the first 40 minutes) but, as soon as "evil" is unleashed, the whole thing turns into a textbook 80's cheeseball! The make-up effects are hilarious and feature for example a giant claw that pulls a heroine into a refrigerator! In all fairness I must admit that I've always been a fan of director Juan Píquer Simon… His "Supersonic Man" was the film that made me start loving bad cinema and even I still regard it as one of the greatest suckfests I ever saw. His more popular achievements, such as "Pieces" and "Slugs", are very cool films since they absolutely shine in the gore department. Cthulu Mansion, however, belongs in the avoidable trash department.

doctorgonzo23 I love B horror films, so I was expecting something that would at least make me laugh or perhaps keep my interest for an hour and a half. This movie was not even close to accomplishing either of those tasks. It amazes me how a production can be so bad in so many ways. There isn't a thing about this movie that makes it worth watching. The acting is bad, and not in a funny way. The actors look bored half the time. It's total s***. Why is it that these productions fail to live up to the standard of high school theatre? The plot is also garbage. The only thing borrowed from Lovecraft is the Cthulhu nomenclature. I mean, what does this movie even have to do with the Cthulhu mythos? Answer: absolutely nothing. The dialogue is so repetitive and inane... not even a bit of humour in it. The characters are also pretty flat. There wasn't a single one I cared about by the end of this monstrosity. The F/X (all 35 seconds of them) are also pretty bad. Again, not funny bad; just plain moronic.The bottom line: I bought this from a local movie store (used) for $1. I should have bought a can of Pepsi, or played 4 games of Space Invaders. I am fanatical about bad trash cinema, especially horror, but I can't find a use for this thing at all. Bypass with extreme prejudice.

ShadowFace_Productions This is the kind of movie that makes you want the hour and a half of your life back. This movie should be in every film class to show new directors what not to do. I saw this movie over a year ago, but as hard as I try, and with other reviews I've read cannot think of a single redeeming quality, other that the ability to MST3K the Hell out of it.

rutt13-1 is one of the most laughably inept film makers I've ever encountered. This movie is hilarious. I don't even remember it too well, i just remember laughing. It's slicker than a lot of Simon offerings, but just as dumb as most. It's just funnier than his earlier works. I like the part where the girl throws the sandwich, which is pretty much all I remember. If you like bad movies you'll like this...
