Corrected entry: Evan resigns as a newsreader when he is elected to Congress. That's can't happen. The US has very strict rules regarding television exposure of candidates for political office, even if it is not campaign related. If the television channel for which Evan works continued to use him as a newsreader, by law they would have to offer free airtime of equal duration to his opponents. He'd have to resign or take leave of absence as soon as he announced his candidacy.
Corrected entry: In the scene before Evan's wife takes away his kids. Evan parks in the U shaped driveway, his Hummer is the only car in the driveway, but when the wife comes outside with their kids her car is also there.
Corrected entry: The steps up to Evans house change. In the scene where he discovers the tools, they are two sets of small steps with a handrail, but when he comes down the steps naked, there are just three steps with no rail.
Corrected entry: When Evan goes to the congress meeting, after he has changed to his "Metrosexual" look with his pony tail on his beard and hair, he is asked to stand up to show support for the new bill. When he stands up it brings a close up to the face for the obvious reasons of re-doing his hair to the "Noah" look. However after the gasp from the audience implying that this change by God has already happened, he makes a slight turn and you can plainly see the original pony tail on his hair still there.
