Continuity: When the former First Lady comes to Dave's office they start kissing. She puts her right arm first around his waist, then around his shoulder. Seen through the office door it's down at his hip again.

Continuity: When Dave is under the shower and the First Lady talks to him the handles change positions many times during the scene.

Continuity: When Dave and the First Lady go to the homeless children's shelter in the President's limo her skirt slips off her knee. Her hands are folded on her left side, as she was trying to lean away from Dave, but when we see the knee from Dave's perspective her hands are folded in the lap.

Continuity: When Dave and the First Lady address the press from the White House balcony, Alan and Bob keep prompting him what to say. As the First Lady was standing right next to him she should have overheard this and get suspicious which, as she told him later during their escape, happened only when they were going to the homeless children's shelter together and he stared at her bare knee.

Continuity: When Dave and the President's wife are going down the elevator to see the real President, right before the elevator stops she unfolds her arms and her hands are at her side. The elevator door opens and her arms are folded again.

Continuity: At the end of Dave's first entrance as President Mitchell in the hotel lobby, Duane grabs him by the arm and pulls him away from the crowd. When the camera angle changes Dave is surrounded by other security staff but Duane isn't there.

Continuity: Dave makes a submarine sandwich for Duane and himself. He is seen shredding some carrot on the still open sandwich, then talking to Duane without moving his arms, and finally there is a close-up where he cuts the closed sandwich into half.

Continuity: When Dave starts acting as President, Bob asks him to call his company to tell them that he is going on a trip. When he makes the call and the camera angle changes the glasses he was wearing are lying on the desk.

Factual error: Nance give the President fertility beads from the King of Togo. Togo is not a Kingdom - it's a Republic.

Continuity: When Dave starts working as President Mitchell after his 'illness' and sits down behind the desk the chair topples over backwards. It's a funny scene but, according to even the lowest office furniture safety standards, absolutely unimaginable.

Continuity: In Dave's final address to the congress, where he declares himself and Bob Alexander guilty of fraud, the papers on the lectern disappear from one front shot to the next, but reappear later.

Continuity: On their escape from the White House Dave and the First Lady get stopped by the police. When Dave starts to act as a Mitchell impersonator he puts on his glasses. There's some fluff hanging from the ear piece which is gone in the next shot.

Continuity: After the all night session with his accountant friend, the next scene shows Dave having a meeting with the cabinet to cut the $650 million. Then he is out in front of the White House in the early morning light saying goodbye to his friend. Those scenes got switched in editing unless the cabinet meeting was held pre-dawn.

Continuity: The DC police cars escorting the president after the "second" stroke to Bethesda Naval Hospital would not have happened that way. Once Ambulance and Presidential motorcade reached Maryland lines (Bethesda Naval Hospital in Maryland) outside DC, then the Maryland state police escort or local county police escort would take over. DC police would not cross into Maryland as an escort.
