HBO Films' BREXIT, Starring Benedict Cumberbatch, Debuts 1/19

BREXIT, starring Benedict Cumberbatch, will debut SATURDAY, JAN. 19 at 9:00 p.m. (ET/PT). The film is an HBO Films, BBC Studios, Channel 4 and House Productions presentation.

The result of the Brexit referendum in summer 2016 caused a political earthquake that laid waste to the normally stable British establishment and sent political tremors around the world. Cumberbatch portrays Dominic Cummings, who spearheaded the Vote Leave campaign. Rory Kinnear plays Craig Oliver, Prime Minister David Cameron's director of communications and head of the Remain campaign.

This provocative feature-length drama goes behind the scenes, revealing the personalities, strategies and feuds of the Leave and Remain campaigns. The tactics employed by Vote Leave during the data-driven campaign swayed a historically silent voting bloc that would ultimately decide the outcome of the referendum, as well as affecting future elections around the world.

BREXIT is directed by Toby Haynes; written by James Graham; executive producers, James Graham, Juliette Howell, Tessa Ross; produced by Lynn Horsford.
