‘Alien Dead‘ is a 1980 horror-film that was written and directed by Fred Olen Ray.
A meteor crashes into a swamp and turns the local residents into zombies who start eater the local wildlife.
They soon become the apex predator in the swamp and have eaten their way through the alligators, so they turn their attention to the next available food source – the people in the local town.
