      Bizarre but beautiful cult oddity

      This strange cult oddity has been all but forgotten since its release in 1972, and I'm not really surprised at that - as while it certainly is a film with some merit, it's also really bizarre and I have no idea who the target audience might be. The name of the title is a demon, who apparently also happens to be the king of hell and who can curse a man to live in incest. Lionello is a man who has been punished by the demon and thus lusts after his own sister; which is not good news for her husband Giordano. If I had to liken this film to other films I've seen, I'd put it in with the likes of Valerie and Her Weekend of Wonders and The Reincarnation of Isabel as all these films are low on plots but high on weird goings on that don't always make a great deal of sense. This film does not benefit from a constantly intriguing narrative but there is usually just about enough going on to ensure that the film doesn't become boring. Director Leopoldo Savona creates a good style for the film and it does look very nice indeed. The film benefits from a handful of beautiful women who don't seem to mind taking their clothes off, which is also nice and care is taken with the locations also. It soon becomes apparent that the plot is not really all that important; but it is at least worthwhile and the script does bother to tie things up at the end. Overall, this is a decent if strange watch and while I wouldn't recommend anyone goes out of their way to find it; it is at least worth seeing.

      A Feast For the Eyes

      "Byleth - Il Demone Dell'Incesto" (1972) is an odd Italian flick that isn't very widely known; while this weird little flick is certainly no highlight of Italian 70s Horror, however, it is definitely a beautifully made film that most of my fellow Italo-Horror buffs should enjoy. "Byleth" is an overall very weird little film, with a somewhat confused storyline which doesn't make a lot of sense. The film makes up for what it lacks in continuity, however, with a very beautiful visual style and intense Gothic atmosphere, a great score, a ravishing female cast (and ravishing female nudity) and a pleasantly bizarre mood. As the title implies, the film has to do with incest, and with an eponymous demon; not wishing to spoil anything, I will not continue with a plot description - but even if I did wish to write a synopsis of the storyline, it would probably take me a long time to do so, as it is so very bizarre and, to put it mildly, doesn't always make perfect sense.

      "Byleth" is not the sleazefest one might expect from an Italian 70s film titled "The Demon of Incest". The film is erotic, of course, and features a lot of elegant and tasteful female nudity. The female cast members (all but one redheads) are all very beautiful, and, fortunately for us, none of them are afraid to bare it for the camera. However, apart from the obvious Incest topic, which is never that explicitly depicted, this one's sleaze factor is not far above average for Italian 70s exploitation standards.

      Set in 19th century Italy, "Byleth" is a nice blend of atmospheric Gothic Horror and occultism and tasteful eroticism, which also includes some Giallo-elements. Director Leopoldo Savona isn't very renowned, but although this is his only Horror film he definitely succeeded in creating a nice mood here. Regular leading man Mark Damon, who is maybe best known to Horror fans for his roles in Roger Corman's "House of Usher" (1960, starring Vincent Price) and Mario Bava's "I Tre Volti Della Paura" (aka. "Black Sabbath", 1963), fits well in his role here, as a young Duke with a somewhat exaggerated affection to his sister (played by Claudia Gravy). But who could blame him? She's hot! The female cast members are the most ravishing sight of this generally beautifully looking film. "Byleth" is shot in very nice locations, with great set-pieces and accentuated by a truly wonderful score. With such a feast for the eyes, a somewhat lacking plot becomes secondary. Apart from its beauty, the film has some moments that are genuinely creepy, though it never actually becomes scary. Overall, this is certainly a 'style over substance' film, but warmly recommended to my fellow Italian Horror buffs, especially to those who appreciate atmosphere and beauty in a film. 6.5/10

      Italian Gothic sleaze.

      A young man possessed by the demon spirit of incest since he was a boy is morbidly in love with his sister.Toss in some female victims,all killed naked with a three-points blade and the fact that this was the first time incest themes were documented in an Italian horror film this way and you have sleazy winner.So I finally watched X-Rated Cult DVD of "Byleth" and I must say that I enjoyed this Gothic mood piece.Strange and atmospheric little horror film that is beautifully shot and has a great score.There is plenty of atmosphere until the climax,which is a big disappointment.Plenty of soft-core sex and full-frontal nudity kept me constantly interested.7 out of 10.

      Decidedly odd at times

      A rather slight but beguiling film that defies categorisation. It doesn't have much truck with a coherent narrative flow either but then it is the malformed or only partly successfully realised films that so often seem to capture the attention of the more jaded cinema viewer. Incest is, I guess, the big ingredient here and the reason why the film has slipped out of availability, but it is linked up with demonic possession too. Oh and rather a lot of naked flesh and erotic goings on. These scenes are well shot and the girls all seem attractive, in fact they also look rather similar to each other, intentionally, I assume, and all but one seems to have red hair. Indeed the outdoor scenes are also attractive and so even when the 'plot' is coming a little unstuck, there is always something beautiful or strange to look at. Decidedly odd at times, this is that little bit different and if there is little blood in the killings we certainly get startling facial close-ups and giallo like wide eyed deaths.

      Not as sleazy as it sounds.

      Countess Barbara (Claudia Gravy) returns home after a year of gallivanting around Europe, much to the delight of lovestruck Duke Lionello Shandwell (Mark Damon, who looks like a cross between Doug McClure and Martin Landau). A couple of problems: 1) she announces that she has got married, and 2) Lionello is her brother (Barbara is a total babe, but that's no excuse). Jealous Lionello proceeds to spy on his sister and her new husband Giordano (Aldo Bufi Landi), including when the couple are making love; meanwhile, a mysterious figure is killing local women with a three bladed weapon. Giordano comes to suspect that Lionello is possessed by the demon Byleth, who causes its victims to kill and live in incest.

      Byleth: The Demon of Incest features plenty of nudity and sex, with some very attractive actresses revealing all for their art, but despite the film's salacious title, it really isn't all that depraved. Shame. With a little more deviancy and a lot more gore (the murders are extremely tame, with just a few trickles of blood), this could have been a classic of Italian sleaze, but as it stand. it's actually surprisingly bland, nothing much of interest happening between the soft-core romps and lacklustre deaths.

      The incest angle finally comes into fruition moments before the end, when Lionello gives in to his urges and Barbara willingly obliges (he's possessed by a demon... what's her excuse?), but the sex is only suggested (keeping it 'tasteful'). Lionello wakes to discover Barbara dead, three wounds on her neck, and goes in search of Byleth for revenge, leading to a rather confusing climax in which the demon appears, looking like Lionello in drag-queen make-up. As erotic gothic Euro-horrors go, this one is merely run-of-the-mill, not nearly as controversial or taboo-busting as the title suggests.
