The Mask (1961) in b/w and 3D on ALOT of acid. Fucked Up!

Primer.

do`nt know the name of the movie it envolved a pig and alot of weirdness,the major actor of the film was Gary Morris I believe ,a black and white film made in the 60`s ,have never seen it again.

tokyo gore police

Human Centipede and Eraser Head

I still can't really think of the absolute weirdest, but "City of Lost Children", "Tideland", and "Delicatessen" come to mind. "Pink Flamingos" was pretty frakkin' weird, too!

Oh! How could I forget...I just saw it again!
"Manos: The Hands of Fate"!
Hey, you said weird. It might suck, but it sure is weird!

i don't really have One movie that strikes me as being the weirdest.
most of the movies i watch are kinda out there to start with.

Gummo was really weird. The Acid House was kinda trippy.
anything by David Lynch might warrant a few therapy sessions.

the gridiron is instilled in the minds of young boys as soon as they can walk. tough guys play football. i am no tough guy. but it's funny a 60 minute game stretched out over 3 hours only has 12 minutes of actual playing time. i find it even more strange that i plan to watch the commercials of a program i don't care for but i rarely watch commercials at all because of my DVR.

Videodrome and Glen or Glenda were both pretty weird and fun.
I feel like I must have seen weirder things, but apparently they weren't worth remembering.

Off the top of my head, Gozu and Xtro.

I used to watch a lot of straight to video shit in my wasted youth so a bit of hypnotic regression would unearth a few gems I am sure.

Valhalla Rising. I would go so far as to regard it as a masterpiece though.
