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’s 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!
