Factual error: The interior shots of the Gemini and Apollo Spacecraft show worn and dirty panels, knobs, switches and circuit breakers. The movie most likely used some original cockpit trainers, but in reality the astronauts were flying brand new spacecraft that were spotless.
Continuity mistake: When the soldiers arrive at the Alamo, the soldier with the glasses is reading a book with a white cover. In the next shot, he is reading one with a red cover.
Continuity mistake: After Bill punches the door open at the end of the alley, the old couple get up and escape. There is a wooden barrel and trash in the corner where they were hiding. But moments later when Batman breaks Bill's leg, the corner is seen behind him and the barrel and trash are gone. (00:05:15 - 00:05:55)Quantom X
Continuity mistake: At the scene of the first shootout, Major Moss is looking at the Construction CEO's passport and speaking, looking down at it. When it cuts to a different angle as the guy next to him asks "War profiteering?", the Major is suddenly looking straight ahead at the female Interpol agent in front of him. (00:09:05)Quantom X
Factual error: The plane used in the film to take Juliet back to London towards the end of the film is a replica of a Dakota C-47. She is painted with black and white "invasion stripes" on both the upper and lower surfaces of the wings - approved in May these were only widely put into use for D-Day in June 1944. After one month the upper surface stripes were ordered removed, and by the end of 1944 they were ordered completely removed. By 1946 when the film is set they would have been long gone from any serving aircraft still flying.Andrew Upton
Other mistake: The Israeli commandos are painting an orange Mercedes black using brushes. In later scenes the car has perfect factory finished black paintwork.
