This is an action/fantasy film set in the caveman era, with some woolly mammoths, mean giant birds and a couple of good looking actors fighting for food and freedom.
Steven Strait plays D'Leh, a strong, dread-locked young hunter who falls for a girl named Evolet (Camilla Belle). She has blue eyes something the Tribe has not seen before, they take her into their village when her parents are killed.
The two are promised to one another by an old prophetess, who also tells of a deadly future for the Yagahl people. Shortly after the prophecy, the Tribe is attacked by "four-legged demons" (actually evil men on horseback). The demons murder or kidnap the strong, including Evolet who is taken to their far-away land in the dessert by a river.
D'Leh and other Tribesmen trek through snow, over mountains into a jungle and cross deserts to find and free their people. Along the way encounters with a larger-than-life saber-toothed tiger and man-eating ostriches who can climb trees build some excitement into the journey.
Other Tribesmen dressed in various costumes with strange hairstyles join the crusade because they have folks who have also been kidnapped.
With spears, arrows and hand-hewn hammers, the challengers are ill-equipped to fight the huge compound of men they find at journey's end. An evil priest uses the captives as slaves to build giant pyramids of stone. It's a scene right out of the Ten Commandments. But, even though D'Leh's small group is terribly outnumbered, they fight with heart and determination.
Even with plenty of action, and for all the fighting going on, little blood and gore appear.
The dialogue is silly, the special effects are sometimes cheesy, especially for a film with a price tag over a hundred million dollars, but the good-over-evil message is strong and that is lots of fun to watch.
