Goofs

During the opening scene when Eddie Foy Jr. asks Reagan if he can go with him on the assignment, his hands are down by his sides in the closeup. but in the supposedly matching medium shot they are on his hips.

When Reagan's Brass Bancroft is hiding underwater from the Mexican police using a hollow reed to breathe, the underwater shots of him show the depth of the water to reach almost as high as the pursuing policeman's chest, but the above-the-water shots show the cop in water that is just only slightly above his knees, clearly too shallow for Bancroft to be hiding.

The fight doubles for Reagan and his villain adversary are clearly doubles in the casino medium shots.
