Visible crew/equipment: During a shot of two of the bar patrons, a man runs past them in the background. The man is director Ben Affleck. He didn't realize it was himself until after he chose to include the shot in the film.
In the scene outside the hospital, after Nick Poole has been shot, Remy Bressant picks up the bottle of liquor, which was capped by Patrick Kenzie and drinks straight from the bottle. The bottle has mysteriously uncapped itself.
