Revealing mistake: In the scene of the first game, the camera pans across the fans at the game. They are mostly dressed in sweaters, coats, sweatshirts, etc. Also, the breath is seen coming from the mouths of the band during their performance. The setting however, is Atlanta, Georgia. The first football game of the season is always in late August or early September. Average temperature during the day is about 90 degrees. This scene was shot somewhere during the winter.
Revealing mistake: The Bears' bus is driving by a green highway sign reading something like "Nutville 2". Road signs are normally made of something rigid. But as the bus passes, the sign ripples in the breeze, and you can tell it's just made of fabric or plastic.
