Z: A Zombie Musical (2007)

There are A-movies. There are B-movies. Then there is Z.

After three Catholic Nuns are attacked by a Zombie Dog and turned into Zombies, they discover a group of articulate, educated, singing & dancing Zombies living in the idyllic enclave of Zomburbia. One of the Nuns refuses to accept her new-found Zombie-osity and sets off on a comic journey of self-discovery and mayhem...with, naturally, much singing and dancing along the way!
