Character mistake: During the scene when AJ is yelling out for any other survivors in his crashed shuttle, we hear Lev calling "A.J.", but with no Russian accent. Then Lev gets his accent back when he says "I'm here." (01:28:10)
Character mistake: When Sharp is teaching AJ to remote detonate the bomb, he says to "lift, press, hold" the trigger device. But the actions with the hands are actually "lift, hold, press." Even AJ repeats it wrong. (02:11:00)
Suggested correction: Lift (the cover), press (the button), hold (the button). That's the sequence.
The suggested correction sequence leaves out the trigger. The original mistake entry seems to be accurate. After watching again, Harry lifts the cover off the trigger, holds the trigger, and then presses the button. Lift, hold, press.
Character mistake: In the President's speech he says that 'The Bible calls this day Armageddon'. That is not correct. In John's Revelation 16 verse 16 it says 'And he gathered them on the place which in Hebrew is called Harmageddon'. Even aside from spelling variations, Armageddon is a place, not a point in time.
