1. Unforgiven - the ending - "anyone who don't want to die best go out the back."
2. Pulp Fiction - the body disposal scene with Tarintino
3. Raising Arizona - the intro to the Lone Biker of the Apocalypse where he throws hand grenades at rabbits.
4. Monte Python and the Holy Grail - Lancealot killing spree
5. Carrie - the very end when the hand comes out of the ground and grabs Sue. That terrified me as a child
