Corrected entry: In the scene where Al Pacino grabs the students phone in his classroom and asks him the score of the Mariners game it is in the bottom of the first inning. According to the 88 minute timeline this puts the time around 10:30am. Major League baseball games usually start at 1pm local time at the earliest.
Corrected entry: When calling in to MSNBC, there could not have been a back and forth conversation due to the 7 second delay.
Corrected entry: During the first television interview with Forester, his first name is spelt "Jon". Later in the movie it is spelled "John" on the television.
Corrected entry: Al Pacino answers the phone in a scene soon after he's given a loaner cell from his student, and he answers the phone with his right hand, which has strangely disfigured fingernails (including a noticeably thick white middle fingernail) and in the next shot, the phone is in his very normal-looking left hand. The same creepy fingernails can be observed later throughout the film.
