Towards the end of the movie, a chyron appears with the text "December 19, 2003, 5 days until the deadline" then a few seconds later it cuts to a shot of the characters' whiteboard with the text indicating the deadline is December 22, 2003 and is 3 days away, contradicting the chyron preceding it.
Camera stabilization is missing in the last few minutes of the movie - not sure if that's intentional or not.
