That clip is from a pretty good Italian movie called "Zombie" that I watched a while back. I watched another movie called "The Beyond" by the same director last night. It sucked.

There was a doctor that was shooting zombies with a .357 in it. They went down with every head shot, however, body shots did nothing (as we all know). I was screaming at the tv last night whenever the doctor was wasting ammo with the body shots.
