Continuity mistake: When Kit gets all the survivors onto the top of the cars, out of the water to keep them "high and dry", Ashley's parents are standing on top of a car next to each other. In one particular shot there's a large distance between them, but in the previous shot they're next to each other. (00:55:50)
