Adventure/drama type.  At the end of the movie there are people in a pyramid or something.  They are in a room.  A booby trap is tripped and they are trapped in it.  The scene cuts to a block of rock that slides down a chute breaking bulbs off as it travels down.  Sand pours out of the broken bulbs and begins to fill the room that the people are in.  A couple of men sit down and accept their fate while a woman in the group acts excitedly.  The film ends with the suggestion that the group are buried alive.
