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.

Continuity mistake: Just before the motorcycle cop smacks their car's mirror off, Gerry says to Karin "You're not British anymore baby." As he does, she raises her coffee cup to her face in the frontal shot. It then cuts to an angle to show him, and suddenly her arm is down, where she raises her coffee cup to her face again. (00:06:05)
Gerry Lane: If you can fight, fight. Be prepared for anything. Our war has just begun.
Trivia: Peter Capaldi, the new Doctor Who for 2014, is listed in the credits as W.H.O. Doctor. Just a fun coincidence, as the roles are too far apart to have been planned, but worth a look.
