Other mistake: When Stackhouse and Burnett are being chased by the SAM, they pull to the right after deploying flares and you hear a voice on the radio say "Chaff, Chaff, Chaff". Chaff is a cartridge of small metal strips released as a countermeasure for radar guided missiles. These small strips add noise to the radar and clutters it up giving the pilot about 5 seconds to evade the missile. Throughout the scene, several indicators such as the flares and exploding fuel tanks suggest that they are fleeing from a Heat-seeking missile, not a radar guided one. To add to this, the voice on the radio wasn't that of Stackhouse or Burnett and was added for radio effect. (00:20:20)
Other mistake: When Rafe and Evelyn are on the platform by the side of the Queen Mary, the platform is going up, but the ropes are not moving through the pulleys.
Other mistake: During the scene when Pilla is killed there is a sniper on the roof of a building firing an AK-47 at the vehicles. If you look at his hands you'll notice they are caucasian. The other Somalis are black. (00:46:25)
Other mistake: The last shots of Trafalgar square you can see twice a UPS van driving in the background.
Other mistake: While in the wooden structure in the trench, a close-up of Ciki's hands reveals that they are pristinely clean. Considering that he has been rummaging around in and out of the trench, and tending to his gunshot wound, his hands should appear at least dirty.
