10,000 B.C. (2008) - 6 mistakes

Revealing: After Evolet got hit by the arrow and presumably dies, D'leh is staring at a mammoth. Behind the mammoth, you can see that the background is a picture.

Other: The men have clean facial hair lines. This could not have happened as they didn't have a tool that could shave as close as a razor.

Continuity: When D'leh is talking to the Egyption "god", he walks up to the army of Egyptians. He walks to within arms length of them, but in the next shot, he's several paces back.

Revealing: In the scene where D'Leh is chasing deer across an open plain, there is a row of 4 to 6 cars with headlights on in the distance coming down a gentle slope.

Continuity: When the 'four-legged demons' catch Evolet leaving objects along the way for D'Leh and others to follow the captives, the leader punishes her by whipping her hands. From behind, two locks of her hair are hanging in front of her right shoulder. In the front shots, four locks are visible in front of the same shoulder.

Plot hole: In the scene where D'Leh kills the mammoth, he throws a spear at it which sticks in quite far and does not droop. A throw from a man would not pierce a mammoth's skin very deep if at all and when the second spear is in the mammoth, the first is nowhere to be found. As for the second spear, even if its rough wooden frame didn't snap under the force of several tons of tough skinned mammoth hurtling into it at a severe angle, it did not hit an area, nor did it go deep enough to damage any vital organs. Had it been a steel shafted razor edge, it may have gone right through the sternum into the upper chest cavity, where it still wouldn't hit a vital organ. And even though the fall drove the spear into a potentially life-threatening position, the mammoth would not have fallen, negating the death in its entirety.
