Let’s dispense with the chit-chat and get down to the Nitty Gritty Dirt Band: Whether you see it as Night of the Demon (the full-length British feature) or Curse of the Demon (the American version with 12 minutes edited out), you’re in for a sweet ride. Based on the M.R. James short story “Casting the Runes” this black-and-white creep-a-thon is required viewing in the horror canon—and if your tender sensibilities can’t fathom a scary movie without a shower scene or diced camper, then I suggest you move on.

Generic 1950s leading man Dana Andrews stars as John Holden, an American psychiatrist and skeptic, who travels to England to expose “devil cult” leader Julian Karswell (Niall McGinnis) as a fraud. The problem is, he isn’t one, and soon Holden realizes the avuncular Karswell has slipped him a piece of paper with a powerful curse on it. (I think it translates as “Hey demon, please mangle and mutilate whatever sorry sack of shit has the misfortune to be in possession of this here paper. K? Thanks!”)

Karswell coolly informs Holden that he will be taking a dirt nap in three days, prompting the spooked shrink and his comely sidekick (Peggy Cummins) to race around the English countryside in search of a solution.

Credit the skills of veteran director Jacques Tourneur for creating a true atmospheric classic. Demon, as well as previous films such as The Cat People, I Walked With a Zombie, and the noir masterpiece Out of the Past (Robert Mitchum’s best movie? It’s up there) demonstrate Tourneur’s finesse with unexpected camera angles and his juggling of light and shadow to create menace.

The attendant legend of Demon concerns the studio’s decision to have a demon appear at the beginning and end of the film, contrary to the wishes of Tourneur. IMHO, it would have been a fine movie without it, but I actually appreciate the effort to give viewers a nightmare they can take home with them. It’s really not a bad demon; I’ve seen much worse.
