Perhaps because I've seen this before it played slightly better this time. A doctor is summoned to a castle where no one will go. Once there no one will admit that they summoned him. It transpires that the daughter of Dr Orloff had summoned him because she was having odd experiences. It transpires that her father has made an invisible man (gorilla) and after a long rambling story in flashback about his the daughters near death, the doctor is locked up, escapes and the castle is blown up. Its at best 40 minutes of material stretched to almost twice that thanks to lots of sequences of people walking the country side, walking down corridors, just walking. It wouldn't be bad if you stripped all of the extra stuff away. Thankfully I was engaged in something else at the same time I was watching it so the tedium was relieved. Worth a look if you're a Eurohorror fan or like the idea of invisible gorillas.

Anyone encountering this film on VHS in the UK as the Invisible Dead, tag line; " god help us if they rise again" will find themselves utterly baffled or just ripped off by the content of the actual film. Not only have they been lead to believe that it's a zombie flick by the sleeve art but the film itself has been sliced and diced, presumably by the distributors following the 1982 video act,so that sleazy content of any kind is absent, and what we are left with is essentially 80 odd minutes of people wandering through corridors very....slowly.....indeed. As others have doubtless pointed out, none of the dialogue bears much relation to the action on screen, some of the soundtrack has been left blatantly undubbed, and that goddamn music clangs away throughout for all the world like a troop of drunken boy scouts assaulting each other with biscuit tins. Listing the inconsistencies and "what the heck?.." moments would take too damn long, but suffice to say that it's one of those eurosleaze offerings that manage to conjure up a surreal, dream-like atmosphere chiefly through being incoherent and flat out badly made.And judging by the speed of the opening doors and "magically" appearing footprints, the invisible ape-man doesn't really pose much of a threat to anyone who can move faster than a relaxed stroll.It's crap. I quite enjoyed it

Everyone else's reviews on here pretty much say what I would say, however, I wanted to add that that music score is quite impressive. I usually don't listen to the music in a film unless it strikes me and this one stuck me as being more than just boring background music. Also, the lighting they used really gave the movie a unique feel. It seemed like everyone was lit up brightly with a light right in their face. It added much needed color to the film. Without the color and music, this movie would have been very drab. Also, the "horror" nature of this film focuses on rape more than anything gory or gross. The rape scene with the maid was too much for me to watch, I had to close my eyes. It seemed to go on forever. Quite unsettling and distasteful. And the ape suit guy was hilarious. Very far from the "superior race" of people the doctor thought he was creating. It seemed like just a dumb ape to me.3/10 because of the music, lighting and unintentional humor.

OK, so the plot is risible, the acting woeful, and the production values worthy of Ed Wood. However this early Eurocine outing is a great "B" movie- at least for those who understand cinematic irony.Crumbling castles, dandyesque clothing and buxom wenches all give it the authentic sexploitation feel. The camera angles add that dangerous and unpredictable quality that only lovers of bad movies can really appreciate.More than that, the film is best known for the most famous bush in cinematic history, that of Brigitte Carva. Oh for the days when women were not just plastic-packed crotch-shaven dollies! The women in this film are real, and the creaking plot makes their naked exploits all the more impressive. For collectors of the genre (or admirers of the hirsute), this B-flick is a must. The plot is only marginally of relevance.
