Continuity mistake: The bottom or hem of Kiri's loincloth keeps changing. In some scenes she is wearing only a G-string or thong underneath. Other times she is wearing flesh colored undies.
Revealing mistake: When Dar approaches the pile of his dead people and lays his dog down over his father's dead body, the father's head raises and lowers slightly from the breathing dead guy beneath him.
Revealing mistake: After Dar awakens following the burning raid, he sees his dog lying dead, several feet away. When Dar picks himself up off the ground, the dog's ear and head twitches slightly.
Other mistake: After the raid Dar's village is burning, left in ruins, and one of the last huts goes up in flames but then explodes like an inferno. Purely for dramatic reasons, rather than just plummeting to the ground like the other burning huts.
Continuity mistake: A thick cloud of steam suddenly appears on the lake between frames while Kiri is bathing. It makes everything more magical, but it's definitely awkward.
Revealing mistake: Every time Dar's village is from the hill, it is a blatant scale model or matte painting where all the people and animals are suddenly missing.
Continuity mistake: By the pier, Dar is either pulling a rope or standing still depending on the angle.
Revealing mistake: When Dar knocks down a bald warrior by the pyramid, the angle cuts and the warrior is replaced by an obvious stunt with a blatant bald cap.
Answer: The creatures did not eat Dar because the eagle landed on him, showing him as a friend to the eagle. They apparently worship eagles, as also indicated by the talisman they give him.
