Other mistake: During the first battle between the Medjai and the Anubis warriors there is a part when all of the Anubis warriors start to get killed off. You can see a Medjai jog across the bottom of the screen from right to left with his sword held out. He runs into an Anubis warrior at the bottom left hand side of the screen and he turns to sand. It's obvious that the guy wasn't doing anything and they just edited in a warrior and had him destroyed. You can tell that the direction for these guys was, "Just run across the screen like you're in battle." Some of the guys are real animated and jump and hack, this guy just looks like he's taking a leisurely jog. He doesn't even swing his arm. (01:47:07)
Other mistake: When they are flying the dirigible through the night you can cleary see that there is a repeated pattern in the stars.
