Cooties (2014)

Watch Cooties: COOTIES is a horror comedy with unexpected laughs and unapologetic thrills. When a cafeteria food virus turns elementary school children into killer zombies, a group of misfit teachers must band together to escape the playground carnage. The film stars Elijah Wood (The Hobbit, Lord of the Rings), Rainn Wilson ("The Office"), and Alison Pill ("The Newsroom") as teachers who fight to survive the mayhem while hilariously bickering in an uncomfortable love triangle on the worst Monday of their lives.
