Factual error: Towards the end of the movie, George W. Bush is seen walking through the Cross Hall of The White House towards what is in reality The East Room. Behind him we see a large staircase with a plant next to it on the other end of the hall. These should not be there: that is where the door to the State Dining Room really is. In the next shot we see W. coming upstairs from a winding staircase that doesn't exist.
Factual error: In the scene where., we see George Bush's speech writers in the final stage of writing the speech, we see a shot of a man working on a computer. The operating system seen on the computer screen is Mac OSX 10.4 Tiger which was released in 2005. The year this scene happened in as noted at the beginning of the scene is 2003.
