Sure there are others, but I tried to think of the ones that you may NOT have heard of. So sit back and relax and feel comfort that you probably haven't seen it (applause if you have). Note that all these films are either from 1992 or 1974...weird.
5.) Man Bites Dog
Country: Belgium (1992)
the jaded viewer says: One of the first serial killer movies that was funny, yet highly disturbing. It's a mockumentary as a film crew follows Benoit, a sadistic serial killer.
So why is it shocking?
Well the fact that our protagonist kills without any remorse and the crew though appalled does nothing the murders and even helps in some cases.
Also the ending is by far ironically twisty. Just a good indie flick but with some of the blackest humor you will ever see in a movie.
4.) Dr. Lamb
Country: Hong Kong (1992)
the jaded viewer says: Sure the easy pick from China is to go with an Anthony Wong Ebola Syndrome flick. But for some unknown reason Dr. Lamb sticks in my head.
Simon Yam stars as Lam Gor Yu aka Dr. Lamb, a disturbed loner who drives a taxi at night, looking to rid the streets of what he considers to be human garbage.
This is Category III stuff which has graphic scenes of mutilation, necrophilia and serious amounts of splatter, gore and carnage.
It's one movie that sticks in my head as the pinnacle of HK splatter and shock.
3.) Benny's Video
Country: Austria/Switzerland (1992)
the jaded viewer says: It's a Michael Haneke film that's NOT Funny Games. Haneke's Benny's Video is disturbing as shit in that arthouse sort of way.
The subject matter is pig slaughter, kid on kid violence and some haunting family issues. It's methodical (as Haneke shows in his other movies) and the violence is a look into Haneke's thesis of violence on film.
It has a lot to say and leaves an impact you soon don't forget. Mostly because of Benny and his video.
2.) Vase de Noces aka The Pig Fucking Movie
Country: Belgium (1974)
the jaded viewer says: It's a movie about a guy fucking pigs...but it's done all avante gardy.
So I will leave you with some phrases because there really is no plot in this black and white grainy film.

1.) Sweet Movie
Country: Canada/France/West Germany (1974)
the jaded viewer says: Coprophilia people. Yup. This movie has it. That's eating shit for pleasure for the uneducated.
But more than that, Sweet Movie loads up on all sorts of no no's that will ban your film in many countries. Pedophilia, real sex on film, childacide.
Read the insane plot at Wikipedia involving 2 separate narratives, one of a "Miss Canada" and the other of Anna.
For some unknown reason the only thing I remember is the second narrative of Anna luring kids with candy and doing the unspeakable to them.
Hell I have no idea what the themes are in this. All I know is my jaw dropped after watching this flick.
********************************************************************Well there you have it. I hope this was somewhat educational. If you decide to hunt down these flicks, be warned you have to have some uber warped mind to get through them. They easily will make you sick to the stomach.
Did I miss one? What are your most disturbing or shocking films you've seen (American or foreign)?
