Pablo Larraín stations his camera tight on Natalie Portman’s face, using extreme close-ups to document the rage that Jacqueline Kennedy shed to bury her husband while the world watched. Forever surrounded by vultures arbitrating her worthiness, her appearance and her politics, Jackie — as portrayed by a career-best Portman — processes JFK’s 1963 assassination in ways that will forever define the Kennedy legacy. In this piercing psychodrama, she becomes the master of ceremonies, trapped in anguish she never summoned. With a script by Noah Oppenheim that’s at once sprawling and alarmingly intimate, as well as a wailing score by Mica Levi, “Jackie” is a fierce act of filmmaking. It’s bold, heartbreaking and revolutionary — just like Jackie Kennedy herself.
