Retro Trailer: "Night of the Comet" (1984)

A comet lands on Earth (or more specifically, L.A.) and turns the majority of the population into dust. It's up to two Valley Girl sisters, Regina and Samantha (Catherine Mary Stewart and Kelli Maroney), to fight zombies, battle evil scientists that work for the government and save what's left of the world. If you like cheesy 80's sci-fi/horror comedies and you haven't seen this yet, then you must do so immediately.
