Natalie Portman's performance in Jackie was the talk of TIFF [1] back in September, and it's easy to see why now that we have a trailer. Portman embodies the role of Jacqueline Kennedy Onassis publicly grappling with the 1963 assassination of her husband, John F. Kennedy. While she is physically transformed — sporting Kennedy Onassis's signature coif and iconic wardrobe [2] — it's her voice and mannerisms that will make you see Portman in a completely new light. The movie is out in select theaters Dec. 2.
