Revealing mistake: During the fight scene in the village between Elias and Barnes, as they roll around on the ground, Barnes "hits" Elias with a right hook and Elias's head is thrown to the side as if he just caught a serious blow. The problem is Barnes's fist quite obviously clears the front of Elias's face by at least 5-6 inches.
Revealing mistake: If you pay close attention to the close up shots of Doug's F-16 dropping bombs or launching mavericks, you will notice that the fighter is a poorly detailed scale model of the real thing. In the scene where Doug drops the Hades, you will notice that he is actually a barely painted figurine and that he suddenly has no headrest/ejection chair.
Revealing mistake: As Sgt. Highway turns the dead body with a cigar in the pocket you can see its right arm move to avoid twisting. (01:38:05)
