This really is a pointlessly small nitpick about a fairly old movie, but in The Mummy Returns, the scene where they're racing to get into the pyramid before the sun hits it. They're racing ahead of this wave of oncoming daylight on the ground, and dive in just at the last moment just as the light hits the base of the pyramid before touching any other part of it.
I know exactly why it's done that way, and it makes for a great dramatic scene in a way that the actually realistic version would not, but seriously, sunrises and tall buildings don't work that way.
