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
