First off, don't watch this film alone! Don't make the same mistake I did, and be sure to watch "Cataclysm" in the company of at least one good buddy, or preferably a whole group of friends. Not because the film is so petrifying, obviously, but for the complete opposite reason. "Cataclysm" is so dumb, so incoherent and generally "so-bad-it's-good", that it'll make guaranteed entertainment for a bunch of like-minded horror lovers! All the necessary ingredients are there, trust me: horribly bad acting performances, totally absurd storylines and plot twists, cheesy early 80s make-up effects, a washed-up Cameron Mitchell, nonsensical dialogues ("I've been staring at these walls so much that I begin to see swastikas in my oatmeal"), Nazi-orgy flashbacks, wooden disco-dancing moves, and the reincarnation of Satan himself in the shape of an Udo Kier look-alike with a very gay haircut. I had seen bits and pieces of "Cataclysm" before, as they got edited into "Night Train to Terror" for some reason, but the full-length version is definitely worth seeking out. Oh, and it's available on YouTube! What are you waiting for? WhatsApp your friends!
