In Lynne Ramsay's postpartum fever dream of a movie, Jennifer Lawrence gives the most complex and bleakly funny performance of her career.

In the genre-blending two-hour film, Lawrence plays a new mother who develops postpartum depression and begins going in and out of psychosis. Pattinson plays her husband; Oscar winner Sissy Spacek and Oscar nominee Nick Nolte play his parents; and Oscar nominee LaKeith Stanfield also stars.

Playing an increasingly unhinged young mother with postpartum depression was an intensely personal experience.
