At last someone got it right. All of these historical films (and I'm surprised no one mentioned 1940's 'One Million BC') are entertainments, not documentaries. License is taken for dramatic effect. If you want history, read a book on the subject. Thank you, Rapaire.

BTE, I believe the move you are referring to is 1966 movie "1 million Years B.C." starring Raquel Welch, altho' Farrah would have been good too.
