You could try The Labyrinth. I saw it for the first time last night and loved it. It's from the 80s, so, unfortunately, the effects aren't that great compared to today's standards. But it stars David Bowie, so...
Well... You could try Donnie Darko. It's not gory by any stretch of the imagination, but it sure does give you that 'What on earth...?!' factor.
Also, try Rubber. It's also not too gory either, but there is a fair amount of exploding heads. It is, however, reeeeeeeeeeaaaaaaaaaalllllllllly weird. Like, you could be on drugs and not be able to get past the first ten minutes (and no, I am not speaking from experience, just quoting someone who is). The whole time I sat there, all I could think was, 'This is not happening...'
I've seen a few people suggest this now and I have to point out, DON'T WATCH FIRE WALK WITH ME BEFORE TWIN PEAKS. The movie is a prequel that came out after the show was over, and it basically focuses on explaining one of the biggest mysteries of the show in detail. Half the fun in Twin Peaks is trying to figure out who the murderer is, and it'll be ruined in under two hours if you watch the movie first.
That being said, obviously, any David Lynch stuff will be good. Also check out anything Alejandro Jodorowsky's done.
I like really weird movies. Like "What the hell what just happened?" stuff. Anything that screws with perception of reality or is extremely surreal or philosophical. The gorier the better, though I hate just hack and slash serial killing stuff. I just want bizarre and strangely filmed. And I like them to be dark.
And nothing generic like Waking Life, Pi, Doom Generation Dark City, etc.
Please and thank you. =)
you NEED to see phantasm if that's your kind of movie. also, ignore the thread i'm about the create dealing with it because it's major spoilers.
These are some of my favorites. Some of these probably aren't as dark as you'd like, but, you asked for strange movies. smile
"A Clockwork Orange"
"Enter the Void" (It's all in first person view!)
"Stay" (One of my favorites--Highly recommend it!)
"The Imaginarium of Doctor Parnassus"
"Pet Shop of Horrors" (The original black-and-white one)
"Paper House" (Not as strange, but really interesting nonetheless)
"The Man Who Fell to Earth"
"The Wicker Man"
"Häxan" (A silent Swedish film. Good luck finding this one...)
"Wristcutters: A Love Story"
"The City of Lost Children"
"The Science of Sleep"
Has anyone mentioned Akira yet? The whole thing was a WTF moment.
Oh, and while these aren't exactly gory or anything, they are odd, and they are some of my favorite movies to watch.
Triplets of Belleville (animated, none of the characters speak, very quirky)
Logan's Run (dystopian, slightly funny in its own special unintentional way with some odd WTF bits)
