Continuity mistake: When everyone is leaving the basketball game near the beginning, watch the crowds around the main characters as they walk down the hallway. Sometimes the extras aren't consistent from show to shot. Ex. At one point a black couple brushes past Ryan - the man is on his right and the woman is on his left. When the shot cuts to the opposite angle, suddenly the man is to Ryan's left and the woman is totally missing. This happens a few times throughout the scene.
