Benedict Cumberbatch will star in a Channel 4 TV drama about the Brexit vote in the U.K., which will be timed to air as Britain leaves the European Union next March. Cumberbatch will play Dominic Cummings, the leading strategist and campaign director of the Vote Leave movement, which sought to persuade British voters to opt for exiting the EU.

“I am particularly pleased to commission James Graham’s hard-hitting and compulsive drama on how the Brexit vote was won with Benedict Cumberbatch in a new role,” Channel 4’s new programming boss, Ian Katz, said at a Channel 4 event in London, Wednesday. “It will be broadcast just ahead of our formal [exit] from the EU in March, assuming that we actually get around to leaving.”

Graham wrote the stage play “The Vote,” which was set on the night of the general election vote and featured an ensemble cast including Mark Gatiss and Judi Dench.
