Banished from their primitive village after the tribe elders deem them too lazy, Zed (Jack Black) and Oh (Michael Cera) leave everything they've ever known behind and embark upon an adventure-filled journey through the ancient world. Co-starring Hank Azaria, Oliver Platt, Olivia Wilde and David Cross, this epic-sized laffer is a collaborative effort from comedy giants Harold Ramis (Groundhog Day) and Judd Apatow (Knocked Up).
