Deliberate mistake: When Baz is driving the 'movie car' the vehicle does not have hubcaps, but in the closeups of the tires there are hubcaps, and the tires change, plus there's tape covering the brand name at the center of the hubcap.
Deliberate mistake: After the AN-12 launches from the carrier, you see U.S. Navy near the nose of the craft, and MG on the tail code (MG=McGuire Air Force Base). Also, during the flight shots, the plane transforms between a C-130 and AN-12 multiple times.
