jetting around town looking for a good vacation 
spot for the weekend, happily married expecting couple Andy (spaghetti western actor Aranda) and Anna (Karr) are approached at a traffic light by another couple in a car. Claiming to be an old classmate of Andy's, Bruno (Guillén) and wife Thelma (Alberti) extend an invitation to join them at their country home for a couple of days away from Madrid. At the house, Andy and Anna spend a little quality time in the bathtub and then join their hosts for dinner, following by that ultimate after-party activity, breaking out the Ouija board. A few nasty revelations later, the marrieds decide to leave but are trapped by a nasty storm. Even worse, Anna hears weird noises at night and goes downstairs to investigate, only to be assaulted by a man in black who disappears moments later. Baffled, the twosome investigate only to find Bruno and Thelma naked, greased , and waiting for them in front of the fireplace... but a little nocturnal orgy is just the first of many strange and ultimately horrific experiences in store over the next 24 hours.
director Juan Piquer Simón 
(a.k.a. J.P. Simon), who wormed his way into the hearts of sleaze fans worldwide by directing such films as Pieces, Slugs, Extra Terrestrial Visitors, and Cthulhu Mansion. This is more accomplished and atmospheric than Simón's usual fare, and much lighter on the ridiculous (but highly quotable) dialogue. Moody, shocking, and wonderfully constructed, this one's a definite keeper.
this disc anyway). Other 
goodies include written liners about the feature and the participants, a rather large still gallery, and that familiar Mondo Macabro promo reel. 
with quite a bit of additional image info visible on the edges and flesh tones now looking healthier and more convincing. The prologue is also side matted to 1.66:1 here to match the rest of the film, which is fine since it's just a guy 
sitting at a desk anyway. The DTS-HD MA Spanish and English tracks both sound great, with optional yellow-ish English subtitles. A new audio commentary with Samm Deighan and Kat Ellinger is an energetic appraisal of the film and its place in Spanish horror, a sort of companion to earlier tracks like Secta Siniestra and all those Larraz releases as they chat about Simón, devilish orgies, other occult-themed films from Spain and abroad, Larraz, pregnant women who smoke, and the joys of Luis Barboo. The fun featurette "Recuerdos de Escalofrio" (46m55s) has Puerto, Alberti, and editor Pedro Del Rey waxing nostalgic about the production including its genesis with Simón, the desire to shoot something quickly with only two available sets, the need to make something for the burgeoning S-rated, adults-only film market in Spain, the DIY street shooting in Madrid, the nervousness levels of the various cast members for the nude scenes, the sources for some of the spooky house decor, and lots more. A gleefully NSFW gallery (1m51s) is also included with various marketing materials including the pressbook. The reversible sleeve art spotlights both the English and Spanish poster art.
blacks and reds look visibly more robust. As usual you get the Spanish and English DTS-HD 2.0 mono tracks, here with 
optional translated or SDH English subtitles, while Jonathan Rigby and Kevin Lyons supply a new, very entertaining commentary track covering the ins and outs of S-classified films in Spain, the occult and diabolism in '70s cinema, the backgrounds of the key actors, and gleeful reactions to some of the more show-stopping moments. "Recuerdos de Escalofrio" and the trailer are ported over, while "House of Diabolism" (48m59s) is a lengthy and enthusiastic appraisal from Stephen Thrower (in fiendish red lighting) who does his usual perceptive deep dive into the film's perverse pleasures and its place in transgressive post-Franco Spanish cinema. In "Rated ‘S’ for Simón" (20m5s), Kim Newman surveys the wild and still somewhat neglected output of the Spanish exploitation filmmaker ranging from his adventure films to cracked sci-fi cheapies to the horror films that put him on the international map. In "Satanic Panic: Diabolic Cinema of the ’70’s" (25m41s), Darrell Buxton surveys the wave of devilish offerings that filled theaters including the likes of this film, The Brotherhood of Satan, The Mephisto Waltz, Psychomania, Blue Blood, Blood on Satan's Slave, Disciple of Death, Virgin Witch, and others that tapped into public anxieties and fascination with covert occult practices. In "Devil’s Music: The Satan’s Blood Composer Speaks" (19m2s), a reframed port of the interview from Severin's Extra Terrestrial Visitors release, composer Librado Pastor chats about his career, the challenges of coming up with strong tunes of movies versus TV, his collaborations with Simón including his gig on this film after doing commercials, and the spooky events surrounding this film like... uh, car problems. He also does a fun 8m41s concert, also previously seen on the Severin disc. Finally we wrap up with "The We Blong Dead Guide to Spanish Horror" (13m24s) covering the beloved spectrum of genre contributions from Jess Franco to Paul Naschy to the Blind Dead among many others, plus a 6m38s image gallery. The disc also comes with an insert booklet featuring two essays, "They Shall Not Pass!" by John Martin on Spanish censorship's effects on Spanish during and after its existence, and "They Tried to Warn Us!" by John Llewellyn Probert provides the scoop on the film's peculiar opening narrator and its debt to other distinctive genre films that presented experts to help us take it all very seriously.Treasured Films (Blu-ray)
