As Deadline revealed exclusively yesterday in its Cannes hot titles list, Natalie Portman has signed on to play Jackie Kennedy in Jackie, a new biopic from Chilean director Pablo Larrain ("No"). The film will follow the first four days in Jackie Kennedy’s life after the assassination of her husband, President John. F. Kennedy.

Deadline first broke the news she was circling the role in 2012. CAA is selling alongside Wild Bunch’s new sales unit The Insiders.

Portman last week signed on to another biopic, that of Supreme Court Justice Ruth Bader Ginsberg, in "On The Basis Of Sex." Focus Features is in talks to finance that one, with Marielle Heller negotiating to direct. Portman also has her directorial debut "A Tale Of Love And Darkness," which she adapted from Israeli author Amos Ozs memoir, getting its world premiere here in Cannes.

Upcoming onscreen turns for her include "Weightless," another Terrence Malick collaboration after "Knight Of Cups," and "Jane Got A Gun," which she also produced.
