Willem Dafoe's character Elias's death in "Platoon"...

that is one of the amazin death scenes...just the atmosphere and the feelins you get when you watch it...arms outstretched towards the heavens...oh boy...

the most disturbing thing about that one is that the pitch of his scream changes as his vocal cords were getting stretched ...
gotta love that kind of attention to detail ,,

ya i remember that. plus the zombie pulls his head off with his finger in both of his eye sockets. OW!

also the other death of that other guy was pretty good too. very atmospheric. He goes from luaghing maniacally to sceaming as the zombies shove their hands into his face and rip pieces off.

actually his back bent bacwards and snapped in half:D

yeah i remember that

We'll it is a classic death scene.

A great one, the guy cleaning the air tunnel in Alien 3 gets spat on by the alien, rols into the fan blade and eplodes :)

Chunks of him everywhere.

Michael Wincott's character dying in the Crow. Falls from the roof, WHAM, impaled on a gargoyle, and blood pours out of the mouth :D
