Nerdy college student Columbus (Eisenberg) has survived the plague that has turned mankind into flesh-devouring zombies because he's scared of just about everything. Gun-toting, Twinkie-loving Tallahassee (Harrelson) has no fears. Together, they are about to stare down their most horrifying challenge yet: each other's company. Emma Stone and Abigail Breslin co-star in this double-hitting, head-smashing comedy.
