JACKIE very well may be the film of the year. It certainly contains the female performance of 2016 in Natalie Portman’s portrayal of Jacqueline Kennedy. And it’s truly one of the most unsettling experiences to be had in a movie theater in some time. JACKIE, which opened this weekend, is a revelatory and intimate movie biography, blending fact and conjecture about the life of the First Lady in the days and weeks following the assassination of her husband, President John F. Kennedy. It is presented as practically a fever dream, a glimpse into the actions and motivations of Jackie during those fateful days. And it stands as one of the most devastating portraits of a public person ever shown on the big screen, her story both horrifying and moving as a tale of unfathomable grief.
