Continuity mistake: At 8:40 PM on September 11th, the sun has not set. The sun would have set over an hour before on that date. In fact, the sun would never be shining that late; sunset on the longest day of the year is around 8:20 PM. (00:39:38)
Factual error: The movie is set in 2012. The S class Mercedes has a stereo camera as a sensor for advanced driver assistance systems, only introduced in 2013.
Other mistake: During the scene when Jack's wife is ordering at McDonald's, the little girls are mouthing the lines as the others are saying them.
Factual error: Sean Smith is shown playing "Call of Duty: Advanced Warfare" on an Xbox. That game was released on November 4th, 2014, over two years after the date of the attack (September 11-12, 2012).
Suggested correction: It was Modern Warfare being shown on the TV. Advance warfare uses exo suits and can't be missed.
