Factual error: In two shots during the Heathrow sequence, a CGI airplane is seen taking off in the background. The airplane is depicted as a British Airways 747-8 Intercontinental. However, BA has never flown this type. They fly the older 747-400, which is distinguishable from the 747-8 by its vertical winglets. The newer type features blended wingtips.
Suggested correction: British Airways did fly 747-8s under the Global Supply Systems brand. These planes still had BA livery, so would look the same.
British Airways flew 747-8F's (the freighter version) circa 2013, distinguished by the shorter fuselage upper deck hump. The airplane depicted in the film has the longer upper deck, common to the 747-8 Intercontinental (passenger version).
Other mistake: During the CIA interrogation Simon's wrist watch shows the time as appropriately 4:25 but the clock in the wall in the same room above him shows the time as appropriately 10:25. (00:39:00)
Suggested correction: So he had his watch on a different time zone. Not implausible in his line of work, and 6 hours is certainly consistent with the difference between the various US and European time zones involved in the story. Character choice or mistake.
Good point about the time difference.
