History was made...by these guys? Zed (Jack Black) and Oh (Michael Cera) are cavemen who stumble out of the mountains into an epic journey of biblical proportions. One is a bumbling hunter, the other's a gentle gatherer, together, they become unlikely participants in history's most pivotal moments. Directed and co-written by comedy legend Harold Ramis (Groundhog Day, Caddyshack, Analyze This), YEAR ONE is rude, crude, wildly absurd, deliciously tasteless and laugh-out-loud funny!
