Natalie Portman's performance as First Lady Jacqueline Kennedy is at the very forefront of this year's Oscar race for Best Actress.

There are performances, and then there is what Natalie Portman achieves in Pablo Larraín’s “Jackie.” In what is easily some of the most powerful work of the Oscar winner’s career, “Jackie” finds Portman burrowing into the soul of Jacqueline Kennedy like never before and forcing the viewer to see her subject in a new, more complex light.

Framed around Jackie’s interview with LIFE magazine reporter Theodore H. White, which took place just a week after her husband’s assassination, the film is a dive into her subconscious as she comes to terms with her husband’s death and rises to the challenge of preserving his legacy in American history. Peter Sarsgaard, Greta Gerwig, John Hurt and Max Casella co-star.

In an A- review out of the Venice Film Festival, IndieWire critic Ben Croll raved, “Running counter to convention at nearly every turn, and anchored by Natalie Portman’s achy-eyed performance, ‘Jackie’ is about the best version of this story you can get.”

Fox Searchlight is releasing “Jackie” in select theaters December 2. Expect Portman to be at the very front of the Oscar race for Best Actress. She’s just that astonishing here. Watch the new official trailer below.
