This film is touted as a Best Picture candidate, and Blanchett has some Best Actress buzz. (She has already won twice, once in a lead, once in a supporting role.) The Hollywood Reporter anointed the film as “a work of genius,” and their review is nothing less than a love letter to Cate and director Todd Field.
As far as I know, that is really Cate, not a double. She is 53 years old, and has never really done any topless scenes beyond some side-boob and a fleeting nipple.
