When Major Lowell says, "We usually don't do that," when talking in his office to Bruce, his hands hold his coffee mug low before his navel, but when the camera changes, his hands are held high, slightly below his collar bone.
When Bruce argues with the referee, he is called for interference and two free throws are given to the other team. The hand signal made by the referee is actually the signal for a technical foul, as there is no such thing as an interference foul. More importantly, referees are not capable of calling fouls on spectators. In this situation, the spectator would be asked to leave, and it would have no impact on the outcome of the game.
At the 1:05 mark, Bruce is ringing his bell but no sound comes from it.
In the night scenes, there are loud crickets chirping in the background despite being in the dead of winter with heavy snowfall.
