Best mindfuck movie of all time

As mentioned:
Dark City
The Crow
Jacob's Ladder

On top of that:
The Serpent And The Rainbow
In The Mouth Of Madness (the book was a lot better)
Inception
The Sixth Sense is up there but not really AMAZING.

Paranormal Activity was a real mind fuck for me personally cause I live in a place that looks just like theirs....lol
 
Everyone above gave pretty much most of what I would have write myself, but I will add:
Donnie Darko which *I loved*
Angel Heart,
A Clockwork Orange,
Memento,
and the (Canadian!) The Cube





I cannot wait to see Inception!

I knew you'd have good taste. Clockwork Orange and Memento were gonna be my two picks. Oh ya, and Teeth!!! I think WD made me sit through that shit, but there were a couple of parts that are a must see.
 
"The Game", starring Michael Douglas and Sean Penn, is worth mentioning.

INTERESITN BUT NOT MIND BLOWING - OK!
 
'Before the rain(1994)' - this one, my friends, is a must see!
It's a perfect example of grandeur rising from the simplicity of emotions- and war. And yes, it meets all the requirements for a wonderful mindfuck. :Spin:
Easily the best movie I've watched in quite a while.
 
Forgive me if it's already been mentioned, but I just remembered that 12 Monkeys made me think "WTF???" a lot.
 
Ah! I was just told about this one the other night, and it (specifically the end) sounded INTENSE. I'd love to see it.

Tell me your thoughts?

Just seen 'Audition' last night after a long time and damn, it didn't lose any of the mind altering suspense. It's like 'The Grudge' meets 'Hostel' with hints of 'Delicatessen' but better obviously.
Have you seen it eventually?
