We really loved Cooties, and now we have an exclusive clip to prove to you why. In it, you can see the all-star cast of teachers—Elijah Wood, Alison Pill, Rainn Wilson, Jack McBrayer, Leigh Whannell, and Nasim Pedrad—trying to get to safety when their charges turn into zombies.

Cooties will be available in theaters and on demand on September 18th.
