Not really a "horror" movie, but that "fire extinguisher" scene in Irréversible was quite brutal!

quite liked the barb wire scene in premutos.not seen mordum,but after seeing a/undergound i understand where elvis christ is comeing from!
m.s.p has some good killings in it.

french movie 'inside'. the whole thing is brutal.

There is a particularly horrific death at the end of a solid yet unremarkable film called 100 Feet, with Famke Janssen.

Its a young bloke being beaten to death by a nasty ghostie, but I thought it was quite effective.

cool I might check that out also the other suggestion sound gruesome too!

Can't go wrong with Visitor Q and Ichi the Killer. Lots of great gore in those two.

Suicide the movie
 

I saw this german nastie a few weeks ago. At the beginning of the film someone wants to off themselves but changes their mind. However, fate has other ideas. They end up on a different floor and in the parking lot at the same time. This is just a taste of whats coming. See it if you can find it. Its worth your while. I agree that Inside was brutal. Unfortunately, what happened in that movie has happened in the real world. The term thats used is post-partum depression. Sad but true

I forgot. Try Meadowoods if you havent already. Very bleak and sad. I guess they call it a "bubble bath and razorblade movie"

awesome man! Also Urdevil many things that are gruesome happen for real so yes they can be sad but they can also be interesting!
