'You never really know what's going to happen'

Jennifer Lawrence and writer-director Lynne Ramsay discuss with Lynn Rusk the challenges of postpartum psychosis in their upcoming film Die, My Love. The film is in cinemas this weekend

- 

Jennifer Lawrence, who rose to fame in her early 20s with films such as Silver Linings Playbook, the X-Men franchise and The Hunger Games, has been portraying maternal roles since the early days of her career.

In the 2013 crime drama American Hustle, the American actress played the volatile wife of a con man, and in 2015's Joy, she portrayed Joy Mangano, a struggling single mother who became a household name as the inventor of the Miracle Mop.

Now 35, the Oscar-winner is taking on her first maternal role since becoming a mother herself. The actress has two kids with her art gallery director husband, Cooke Maroney.

In Die, My Love, Lawrence stars alongside British actor Robert Pattinson, 39, as Grace and Jackson, a young couple who have recently moved into an old house deep in the countryside.

With dreams of writing The Great American Novel, Grace settles into her new surroundings and the couple soon welcome a baby.

But as Jackson becomes increasingly and suspiciously absent, and the pressures of domestic life mount, Grace begins to unravel, leaving a trail of destruction in her wake.

Directed by Scottish filmmaker Lynne Ramsay and based on Argentinean writer Ariana Harwicz's 2012 novel of the same name, the film explores a woman driven to the brink of insanity by marriage and motherhood.

The film also stars Sissy Spacek as Jackson's mother Pam, LaKeith Stanfield as Karl, a motorcyclist who occupies Grace's fantasies and Nick Nolte, as Harry, Jackson's deceased father.
