Did You Know?


The film's screenwriter Patrice Rondard, who frequently used the pseudonym Patrice Rhomm for his literary and cinema industry work, also wrote a novelization entitled Au service du Diable. The 216-page French language paperback was published by Galliera in April, 1971 to coincide with the film's European theatrical release. Galliera issued the book as the first volume in their Bibliothèque de l'étrange (Strange Library) series. It features a full color illustration on the paper cover depicting Erika Blanc and Daniel Emilfork as their respective characters that is moderately different from the artwork used for theatrical release poster.

Very scary shocker from Belgium/Italy
17 October 2006 | by vampi1960See all my reviews

I saw this as one of 10 horror films on a collection from brentwood DVD called;fright night,its an awesome collection of fright films.anyway the devils nightmare is a Belgium/Italian made shocker about a group of tourists(each one represents one of the 7 deadly sins)they get stranded at the castle of an ex Nazi officer.there's a family curse,gruesome murders,lots of nudity(surprising for 1971)and a very good soundtrack. I'm usually a sucker for good European horror movies especially with the sexy beautiful Erika blanc,who starred in many Italian horror films.sort of like a rival of Barbara Steele.the murders are very gruesome.the dubbing is sloppy but thats expected.i saw this years ago on the USA cable network,of course it was chopped up by the censors. it was hosted by commander USA.who used to show very strange movies. watch the uncut version for the full effect.ignore the critics because most of them dismissed this film as junk.you be the judge.believe me its kind of scary.8 out of 10,Erika blanc gets 10 out of 10 because she was hot.
