When Gage is in the dirt tunnel digging and trying to rescue the Diaz child from the hole, his clothing switches from being mildly dirty to very dirty. After the rescue, when he emerges from the tunnel, his clothes are only mildly dirty.
John and Roy are preparing to dig the trench out to remove the stranded horse. Roy produces a full size, round point shovel with an approximately 4 foot handle from a compartment on the back of the squad The door to the compartment is only12 to15 inches wide. He is holding the shovel perpendicular to the compartment door. It would be impossible to remove a shovel of this length sideways from the opening.
As the three men are facing forward on the boat, there would be winds blowing toward them as they are speeding along. None of the men's hair is moving.
Assuming that Roy & John were actually on a speeding boat, they violated the most important of regulations - they failed to put life jackets on. Second, they were standing up in a badly bobbing boat instead of sitting down, also a mandatory safety requirement.
