Continuity mistake: Vale's left eye (or possibly both) change to white in his transition/death on the plane. However when he is walking towards others the others before being shot it is his right that is white. (00:28:00 - 00:29:00)
Continuity mistake: When Ahmanet enters the Crusader burial chamber, she walks in holding the dagger with her right hand and then picks up the stone. As the camera takes the close up shot, it is very clear that she picks up the stone using her right hand. When the shot changes, she is now seen holding the stone with her left hand. (01:22:55)
Continuity mistake: When Nick goes flying after being hit by Ahmanet, he is without the dagger, but when he gets up, the dagger mysteriously re-appears in his right hand. (00:29:18)
