A new reason to revisit this intense 2012 war film directed by Kathryn Bigelow, written by Mark Boal? Not that you should need one, but here’s one anyway: Watch for the small but crucial appearance by the late James Gandolfini, who plays a powerful politician critical to the continuation of the plan to find and target Osama bin Laden. He plays the part perfectly, with strength, compassion and not a little humor – which, come to think of it, were three of his strongest attributes as an actor. Jessica Chastain stars.
