The Beast 1975 Written and directed by Walerian Borowczyk. A French erotic horror film that's vaguely adapted from the novella Lokis by Prosper Mérimée. Someone gave me the Arrow DVD, looks pretty good and there are a few extras.
Lucy is daughter to the late Philip Broadhurst, his will says she has to marry Mathurin, the son of Marquis Pierre de l'Esperance, within 6 months or she gets nada. Lucy and Aunt Virginia are driven to Mathurin's horse breeding farm. They are greeted with some horse sex in the courtyard.
Lucy hasn't meet Mathurin and doesn't see him when she arrives. Mathurin is a hairy guy, he needs a shave before he can meet anyone. Lucy is given a book about a local legend, Romilda had a fight with a bear 200 years ago, a fight which turned rather rapey. Lucy comes across several erotic bestiality drawings. Lucy dreams of an erotic encounter between Romilda and the beast. He's well endowed and proud to show it off.
The beast's costume is lacking, it makes him look like a bit Muppet like. Not the penis so much, mostly his face. Sadly, they take a lot of shots of that wang, pumping goo and not pumping goo. Then Lucy finds her fiance dead. They pull some clothes off Mathurin revealing his claw hand, his hairy back and tail, Lucy freaks out and runs around the house naked, screaming bloody blue murder. Lucy and her aunt leave the farm.
Somehow this has become a classic in the world of monster erotica. It's slim pickens I guess. I saw it back in 1997 and didn't think much of it back then but I did like the naked ladies running about. I must have watched it again in 2009 and liked it less, I rated it a 3 on the IMDb, I'd give it a four nowadays. It's still not very good but I laughed a good bit. Mostly because it's rather ludicrous.
