Other mistake: When Jackson and O'Neil are captured and taken before Ra, the guards hit their knees with their staff weapons to make them kneel. Jackson's guard does it right, but O'Neil's misses him completely.
Other mistake: When the team are headed to Ra's pyramid dressed like Egyptians, the door starts to close with about half a metre left. After another shot elsewhere, when it faces the door again it has more than half a metre until it hits the ground.
Other mistake: When one of Jackson's crew raises his 35mm camera and takes a picture, there's no lens on the camera.
Suggested correction: Yes, there is. You can see the glass lens at the end if the lens reflecting light as the angle of the camera changes. If a lens wasn't there, there'd just be a hole in the front of the camera body. The lens is very short, presumably a wide angle, which might give the impression of there not being one.
Other mistake: When the ship lands atop the pyramid and begins to retract and open the topmost sections of the pyramid retract into the lower parts however the upper parts are too long to fit into them. In the next sequence we see the ship and the upper parts are nowhere to be seen.
Suggested correction: Perhaps the parts fold further in on themselves. Like a retractable ladder.
