Visible crew/equipment: Near the beginning of the movie, after the simulated alert when all of the government officials are getting into their cars to leave, there is a visible film camera, camera stand, and the camera operator. The reflection appears on the rear passenger side of a car on the right side of the screen. (00:08:10)
Continuity mistake: In the aircraft scenes after the blast in Baltimore, watch the clocks closely. The times go forward, backward, and everything in between.
President Fowler: Order the planes to stand down, take us to DEFCON-3... and will somebody ask Mr. Ryan if I can use the phone now?
Trivia: The SuperBowl game was filmed in Montreal, Quebec in Canada and the two teams are the Montreal Alouettes and Toronto Argonauts of The Canadian Football League. They just put them in different uniforms to film them.
Question: As President Fowler is being escorted from the football stadium, he tells Cabot to "get the people out of here." How did the President know that the bomb was in the building? No one in the scene knew its exact location, so why does he think that if the fans leave the stadium they will be safe?
Answer: He likely (and correctly) assumed that, because he was being evacuated in such a hurry, his current position was either Ground Zero or somewhere close enough to be affected - especially once he is practically thrown inside his limousine and held down.
Answer: The President telling Cabot to "get the people out of here" is just a political life boat. If asked what he did when he found out about the bomb he can "honestly" say he asked for an evacuation.
It's unlikely at such a time of panic that one would consider a 'political life boat'. There's also nothing in the character as presented to suggest that would be his thought process. The president's just been told that there's a bomb in Baltimore (not the building) and says "get those people out of the stadium." He's being evacuated from a location that contains thousands of other people. It's fair to assume he knows all those people are also in danger so wants them evacuated too.
