Other mistake: There is a scene where a dead Indian warrior is discovered. In this scene he is covered by a large flat piece of stone. When they pull away the stone you can see his chest rising and falling as the "dead" Indian breathes. Much easier to see when viewed in HD.
Revealing mistake: In the scene out West with the buffalo, notice the car driving in the distant background.
Revealing mistake: When the parted Red Sea comes together, if you look behind Pharaoh as his troops are being engulfed by the water, notice in the background that there are two boulders floating in the water, not being pushed, but floating lightly.
Continuity mistake: When they are dancing the king's earring is on his left ear then it somehow jumps across to the other ear.
Continuity mistake: In the final shot, just as the credits are rolling, the British warships are sailing away with the sun setting behind them. In an earlier scene the radio commentator says that the sun is setting and a shot of the sun touching the surface of the sea is shown.
