Ask any kid on a school playground and they'll tell you that getting cooties is just about the worst thing that can happen to you. Well, according to the movie Cooties, it turns out the kids were right. Cooties is a horror-comedy where a virus is passed to school kids via chicken nuggets, turning them into face-eating zombies. The hilarious cast includes Rainn Wilson, Elijah Wood, Jack McBrayer, Alison Pill and Nasim Pedrad, as well as writers Leigh Whannell (Saw, Insidious: Chapter 3) and Ian Brennan (Glee).
