Corrected entry: 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. (00:58:50)
Corrected entry: 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. (00:34:25 - 01:06:25)
Corrected entry: Dave is watching Jay Leno but you can see the Grandfather clock on the wall, and it's not time for Leno. (01:25:50)
Corrected entry: When the tour guide is leading the group through the White House, she says that 42 presidents have occupied it. However, when Vice President Nance is sworn-in, the newscaster in the background says he is becoming the 45th US president.
Corrected entry: As Bob is walking out of the car to make his speech about President Mitchell there is a group of visible people standing across the street watching the scene being filmed.
Corrected entry: Dave gets briefed by Bob Alexander and Alan Reed about the basic aspects of a President's routine. They use all kinds of fancy tools, such as life-size cut-outs of the staff members. How on earth did they manage to get those made and brought into the staff meeting room without anyone noticing, as they (and Duane) were the only ones close to the President who knew about Dave's identity?
