Most disturbing death scenes in sci-fi/horror movies?

@whiskuz, thanks for reminding me of that SICK movie that I couldn't stop watching! That scene caught me off guard, along with the sheriff bake and barbed wire douche, ouch. There was some funky Italian film, I think Suspiria that was kind of jacked up too. I have an aversion to barbed wire and razors now. I saw previews for some Spa of death movie where everybody in the spa got yuckied, didn't watch it based on previews, very gory. I think the deaths that suck the most is like what was happenning to Dallas (turning into a face hugger, and skeleton key, knowing whats happening to you and having time to think about it. I say if I can't go peacefully in my sleep, make it quick!!!

Well, the ending of "Martyrs" is one of the most disturbing "death scenes" that I've ever seen...it's not that it's overly bloody, or painful looking, but it's the most disturbing one psychologically and physically. See it if you haven't...and see it in the original French before it gets made into some stupid Americanized version (which I think they're working on)...

Sci fi horror......rules out the whole last 20 mins of Audition then Has to be Scanners for me...you know the scene I'm talking about.

the guy spacing himself in the airlock in outland. and the air lock is full of exploded entrails. its pretty grusome.

.....maybe not the most disgusting scene ever but one that made me jump so bad i spilled my coke and popcorn all over the place....in the first grudge movie when that chinese chick goes up to the celler holding the lighter and that white faced mother ghost rips her yaw off...you don't see what happens......but later in the movie when you see the ghost minus her bottom yaw......you can pretty much figure out what happened.....but i nearly shat myself....for some reason that is one of the few movies that ever left me awake....oh and the transformation scene in American werewolf in london. Disturbing movies scene's would be that scene where they bludgeon Joe peschi to half to death and then bury him alive!....also some scenes from the blob!

otto: Martyrs - every bit as disturbing as it is brilliant. And the ending sticks with you for a looong time. and you're right, it'll get watered down and ruined if it gets Americanized. I can't think of ONE horror film, from Let the Right One In to REC to The Vanishing to [enter name here], that wasn't ruined by an American remake.
