Z: A Zombie Musical(2007)

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!
