‘The Boy’ Director’s ‘Separation’ Casts Up With Brian Cox and Mamie Gummer, Among Others

The next horror film from director William Brent Bell (The Boy, The Devil Inside) is titled Separation, and as we recently learned, Rupert Friend was the first to join the cast. Deadline updates today with more casting, announcing that Brian Cox, Mamie Gummer, Madeline Brewer and Violet McGraw have now also signed on.

The film takes on the horrifying consequences of divorce, and is being described as a cross between Kramer vs. Kramer and films like Sixth Sense and Mama.

Friend and Gummer will play Jeff and Maggie, a newly separated couple battling for custody of their 7-year-old daughter (McGraw).

Brewer will play the couple’s longtime nanny, and Cox is Maggie’s overbearing father.

Nick Amadeus and Joshua Braun penned the script.
