Some movies are to be taken serious, this is not one of them. It's a comical look at prehistoric life. It's not supposed to be accurate in historic detail, it's supposed to make you laugh and this movie did just that. Ringo Starr is great as the unlikely hero Atouk and his wife at the time, Barbara Bach plays the sexy prehistoric temptress wonderfully. Watch for scenes with Shelley Long and Dennis Quaid and you get a glimpse of their early careers.
