Its not a horror flick at all, but still the best decap of all time....Gladiator, when maximus sticks the two swords in the guys chest, looks at him fer a second, then takes em out and lops off his head w/ a scissors motion. Oh, and horror wise, i thought when jamie lee curtis decapped "michael myers" (I quote that bc it wasnt him) in H20.

One that sticks out in my memory is in "audition" when she walks up behing the old guy playing piano, wraps razor sharp wire around his neck and wrenches his head off with a sharp tug.

I like the scene in Serpent and the Rainbow when the one guys rips off his own head and then throws it.

My favorate is tied between two Wrong turn:(seinario) girl in tree mest up looking guy be hind her in tree, axe, head sits on axe, body falls, looking at the girls eyes why the life drains out, (great movie, wouldnt recommend eatting why watching), second favorate is in Thirteen Ghosts (seinario) Guy walking in basement, steals money, see ghosts let ghosts out, looking at ghosts glass comes down, looks like nothing happeaned, front of body slides down glass, back of body slides down glass, These were great parts of the movies.:D
