"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

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.

I only have a brother, and I hardly ever get the urge to shag him, so the subject of incest is all new to me. Byleth explores the subject by placing it in a more superstitious era, mixing it up with a possible supernatural angle, throwing in a whole load of nudity, and confusing the crap out of me to boot.

Mark Damon has a sister whom he likes. Really likes. He's a Duke and stays in a big castle with loads of staff giving him the glad eye but the film heavily implies that the only thing that gets Mark up and angry is his sister, played by Claudia Gravy. That's a problem, because Claudia has just returned after being away and she's got married during that time. The other problem is the serial killer going around killing red-headed women. The other other problem is that there might be a demon involved, and the other other other other other other problem is that the demon might be possessing Mark! How's he supposed to get into his sisters knickers with all that going on.

That amount of stress would usually kill all the romance dead in the water, but this is a seventies Italian film and therefore everyone's as horny as a Glaswegian lass full of blue WKD. This helps the director pad out the film with endless wriggling sex scenes that look about as natural as Kim Kardashian's arse. Mark does a lot of spying on people as well during this film, and every actress has red hair and looks similar, so things become confusing really quickly.

Is Mark possessed by a demon or is that just an excuse for him to frottage his sister's leg? Who is that guy he keeps seeing on the horse who kind of looks like him but might not be? And what happened at the end?

No really - what happened? It didn't make sense to me.

This is surprisingly watchable due to Mark Damon acting mental. He also played a guy who wanted to boff his sister in Crypt of the Living Dead.
