I have so many movies left to watch. The fact that this exists and I have never heard of it...is confounding.
The immediate comparison I made in my head was to Jess Franco's Oasis of the Zombies. It has been years since I saw that but in my head it's this slow hazy nonsense movie with vague zombies and basically no plot, and if that doesn't describe that movie well it certainly does describe this movie.
Some French production originally called "Once Upon a Time...the Devil", this the last movie by director Bernard Launois. It consists of what I will guarantee you are more sounds than words and more specifically noises made by a horse instead of dialogue.
A ship crashes into a hill, a horse bucks around whinnying like mad, a mummy walks around, a undead zombie creature goes around killing people, and all these things are maybe linked, but definitely not clearly linked as our main heroine runs or hollers or fails to react at all. Like I said, there's not even much dialogue in the movie and a lot of scenes play out with nothing said, explained, understood or communicated whatsoever.
Devil Story I guess has a cult following, in that hallowed hall of movies claimed to be the worst. In the end, another inexplicable scene happens and it doesn't even make you blink. This movie like no other trains you to just sorta take it in stride, blink, say uh huh, and just sorta detune yourself one more step and step outside of reality a little more.
There is value in this, its hard to define, but I do like it, and I give it about 4 stars.
