Return of the Living Dead introduced a lot of new ideas to the world of horror and one of those was the unstoppable zombie. Early in the movie a cadaver meant for a medical school gets exposed to the deadly zomibifying trioxin gas from the basement of the building and starts running amok. He has to be dealt with so the survivors let him out and drive a pickax through his head. After all, that’s what they did in “that movie.” They destroyed the brain to kill the creature.
Problem is, it doesn’t work.
In fact the zombies in these films are so powerful and indestructible that nothing short of total incineration will stop them. Cut off a hand and the hand keeps coming. Cut off the head and the body will keep running around while the head bites at you from the ground. It’s a horrifying idea that nothing you do will ever work and it first came to us in this brilliant scene with the incredible yellow cadaver.
