Continuity mistake: As the President leads the staff out of the Oval Office, the rear angle shot shows Kate Harper is ahead of Annabeth Schott. But the angle reverses to show them emerging from the office as Kate is coming around Annabeth's right side to pass her. (00:40:00)
Continuity mistake: When Kate Harper and Sec. Hutchinson are arguing about the hostages in Bolivia, the digital clocks on the wall behind Kate don't sync properly as the shot switches between the two of them. (00:30:15)
