Factual error: In the beginning, when the President and First Lady disembark Marine One and walk toward the White House, you see the White House. The problem is that it's a set and only the center of it appears. The East and West portion of the main mansion are just sunny blue skies. (00:01:50)
Factual error: When the real president is shown in a coma in the White House basement, he is on a ventilator (a breathing machine). Ventilators require that the patient be intubated (a tube placed into their windpipe) and cannot work with an oxygen facemask which the president has. (01:02:40)
Factual error: At the beginning when Dave is imitating the president in the car dealership commercial, he's talking about the specials on the Geo Storm and Geo Storm convertibles. Geo never made a Storm convertible. The only convertible car sold under the Geo nameplate was a convertible version of the Geo Metro, based on the Suzuki Swift.
