I've watched Three Extremes and Audition so far. They're good, but they aren't what I'm looking for. Having talked to some friends, I think I'm going to have to order the August Underground flicks.

The first one is tame and quite an average film don't let it put you off Mordum and Penance which are brilliant IMO. Mordum has some pretty vile scenes especially towards the end.

Have you seen The New York Ripper? Its quite a twisted flick.

extreme,id say that the a/underground and slaughtered vomit dolls are about the most extreme ive got.haute tension is quite graphic but has also got a good story and twist.make sure,has with all horror you view the uncut version.

Salo, The 120 Days Of Sodom - an Italian movie made in 1975 based on the novel by the Marquis De Sade. Seriously disturbing!

If you liked Martyrs then try High Tension and Wolf Creek
