Add to that the weird atmosphere of the mid-1970s where the Flower Power generation settled down into a marketable demographic, Italian Giallo was in its golden age, and a general revival of interest in horror, and you have a formula for chaotic confusion. Film culture at large went scrabbling for any demon-possession yarn they could get their mitts on, accompanied by the stock effects tropes: must either (1) spin head, (2) puke glop, (3) talk in a creepy voice-over, (4) levitate furniture, or preferably all of the above.

Without further ado, roll that demented demon footage!

Enter the Devil (1974)

Wait, I thought the whole point of demon possession was that the devil enters you! Anyway, we open with a whole chapel of singing nuns (Catholics! Taking up one-half of the horror genre since 1973!) while our hapless possessee has a Satangasm. And then we get this infernal Hell vision that starts out with Jesus (presumably) breaking down off the cross, apparently pissed about being crucified and looking for revenge... and you won’t BUH-LIEVE what happens next! In case you’re curious, we’re told the rest of this movie is so depraved and sleazy that the trailer is practically showing you the tame parts. You want Giallo, you got Giallo!
