"I Saw The Devil"
Yeah I liked that one.
If you like that, I'd also recommend this:

It's another taut Korean thriller, not as dark as ISTD but still quite good (y)
"I Saw The Devil"
Requiem for a Dream is pretty disturbing to most but no violence or gore.
A Serbian Film
Salo, or The 120 Days of Sodom
I've watched real gore stuff before, too.
"High Tension" is a very twisted, intense, disturbing movie, but not quite as challenging as Frontier(s).
someone mentioned "Enter the Void"
Human centipede.
another by the name of "Itchi The Killer", not sure if that is also Korean or Japanese.
Did anyone mention Battle Royals? One of the most bad ass movies ever!
@TheLoveBandit Have you seen ‘Oldboy’ by Park Chan-Wook?
the origional oldboy is the best sadness with violence at it's best ...Yes you have to watch ‘Oldboy’ Park Chan-Wook only! Spike Lee tried to do a remake and I spit on it. I’ll never watch it. Only watch Park Chan-Wook. It’s worth it, especially for the twist like I said.
"Itchi The Killer", not sure if that is also Korean or Japanese.
Begotten (89) is a bit different. Not the most disturbing, a little arty.
I guess I find real-life more disturbing than films. I don't care for horror, I guess I have trouble suspending disbelief sometimes. The documentary Jesus camp was definitely more disturbing than many horror films. Same with Titicut follies, though I was in Massachusetts at the time.
I saw that, and it was all kinds of nasty. And you’re right about the noises. Awful.That ones pretty bad yeah.
Don't think I've seen the face peel one, some of the Mexican cartel beheadings are pretty raw though yeah, seen the one where its 2 guys (I think they were informers) and one gets chainsawed and the other gets done slowly with the knife? The wheezing noises coming out of his neck after were quite disturbing, stayed with me for a bit haha
Just google cartel face peel and it will come up. U gotta see it
U hear the guns n roses playin lolOk, that just moved up the list past 3 men and a hammer. Insane.
But both are actual events, not films, so probably not for this thread (or perhaps even for the site).
3 men and a hammer.
Jesus is shit is a an actual film featuring wtf Scarlett Johansson and myself but no one is allowed it.
