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.

Jennifer Lawrence and Robert Pattinson are currently in Cannes promoting their new film, Die, My Love. And while the movie has brought up some heavy topics—postpartum psychosis, marriage troubles, etc.
