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.
