This film is a fascinating case study in making a film almost entirely about the life and presence of a person who the audience doesn't often see. The sparse visual presence of JFK in this film may have been both a writing and directing strategy, so the audience could focus on Natalie Portman's Jackie rather than on JFK and the actor's resemblance, voice, etc., all of which may have been distracting. One of the most masterful aspects of Portman's performance is the way she balances Jackie's duty to JFK's legacy while experiencing a visceral grief that is distinctive from the country's grief: while everyone lost their President, she lost her husband.
