Insanely Brilliant 70's Junk!
30 October 2007 | by (the Draconian Swamp of Unholy Souls) – See all my reviews

Movies such as "The Devil's Nightmare" are exactly the type of cinematic smut I live for! It's got everything to magically conjure a gigantic smile on the face of every slightly deranged horror/cult/exploitation fanatic. There's bad & incoherent plotting, macabre set-pieces, a mild Gothic atmosphere, demented characters, shocking themes, lousy gore effects and – not to forget – authentically gratuitous lesbian sex! This Belgian/Italian co-production (love the combination since I myself am Belgian and Italy is my favorite movie-making country) is messed up beyond proportions and describing the essence of the plot would take up at least a couple of pages, so I won't go too much into detail. Let's just say the main storyline revolves on an ancient family curse that turns every first born daughter of the Von Rhoneberg generation into a succubus (= female servant of the devil), and a group of tourists stranded at the family castle are just in time to "celebrate" the devilish pact's 700th anniversary. Furthermore, the baron practices alchemy in his basement, there are Nazi child-executions, a gruesome murder story for every room in the castle, the random torture of cats in the attic, negotiations between a priest and the devil himself and a wide variety of shlocky massacres. A lot of the on screen events don't make sense, and there's no building up suspense whatsoever, but it has to be said that the screenplay does also feature a couple of ingenious and rather clever elements. For example, the Succubus (a luscious Erica Blanc) makes sure that every tourist's death symbolizes his or her biggest sin, whether it's greed, unfaithfulness, curiosity … The killings are very nasty, though hardly scary, and follow each other at an incredible pace, barely allowing you the time to wipe the sinister grin off your face. And if all that isn't enough just yet, wait till you witness the far out climax sequence. Oh yes, "The Devil's Nightmare" is pretty bad… So bad it's freaking brilliant! Easily one of the most entertaining European exploitation movies ever made. It's ten times more exciting than all Jess Franco's movies combined, sleazier that Jean Rollin's horribly dull vampire movies and more demented than … well, anything you've ever seen. It's a damn shame Belgians and Italians didn't collaborate more often back in the 70's, because this crazy puppy is a real keeper.
