A Feast For the Eyes
11 January 2010 | by (Salzburg, Austria) – See all my reviews

"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
