Original Australian Daybill movie poster. Encino Man shows just how hilariously out of control things can get when the Stone Age meets the Rock Age head on! The fun kicks off when two high school buddies dig up a frozen caveman in their backyard. Once the living fossil thaws out, the friends figure heâ€™s their ticket to being cool! But the plan backfires when the newcomer turns everyday life upside down, generating pre-hysterical craziness wherever he roams!
