Most gruesome movie scenes?

[CompanyScum]

The string sawing (manipulation) of the dad in Audition.

Oh my, good choice Lions!
Such a unique scene beause he keeps going from fantasy back to reality. haha.

[Ninth Delegate]

The whole home invasion scene in "High tension AKA Switchblade Romance"; especially the part where the father gets his head trapped in the bannister then has it ripped off his shoulders when the attacker rams a chest of draws against it.

[Cowboy Is Cool]

The scene in Irreversible where the guy gets his skull crushed with a fire extinguisher.

Damn! You beat me to it. That film still messes me up! You realize it's the wrong fella too, right? Absolutely flippin' crazy stuff.

As an alternative then, I'd have to say the dodgy ending to a german flick called 'Nekromantik'. It may be hilarious in a way, but it's still just WRONG! Ain't no way I'm posting a link either...

Ignore the sex scene with the decapitated head, as its there to throw you off and not reveal who the killer is.
The girl on the dvd cover is in love with her best friend.  In order to win her love, she invents a scenario in her head that a homicidal maniac has kidnapped her friend, and if she rescues her, the friend will be "grateful".  Basically, its a lesbian masturbation fantasy of a mentally ill woman.

This, hands down. Seriously, don't watch it if you have a weak stomach. The sound effects make it even worse.

Some scenes in the Texas chainsaw massacre are very gruesome like when leatherface puts people on the hooks.

Another stunner!

I fully understand where you're coming from with the brotherhood thing. That was just HORRIBLE to watch... but what done me in the most was the fact they were still breathing (very very slightly, mind) as they were being buried.

Yuk, yuk and yuk. All in all though, I'm still gonna have to 'dig' it out and watch the bugger! 

[yids-warrior]

yeah yeah totally haha that makes it so much worse! its like at the end of SAW when jigsaw just shuts the door on him haha that played on my mind for a while also!imagine just being locked in a room in the dark alone to die with no one to hear your screams for help  horrendous predicament to be in hahaha
