Seven Mummies (2006)

Continuity mistake: In the opening scene, two people are dragging a coffin through the desert. After first seeing only their boots, when we see the two guys, the one wearing a white shirt is on the left, and the one with a red shirt on the right. But in the very next shot their positions have changed, now the man with the white shirt is on the left while the one with the red shirt is on the right.
