The 'Sherlock' actor will star as Dominic Cummings, the strategist who was the campaign director of the 'Vote Leave' campaign.
"Unpacking the anatomy of the historic, high-stakes campaign to win the hearts and minds of the British people, this one-off drama set primarily during the referendum will, for the first time, explore the myriad tactics employed to swing one of the most surprising referendum results in living memory," Channel 4 said, as reported by The Hollywood Reporter.
The drama will be directed by Toby Haynes and written by playwright James Graham.
The film will go on floors later this year. (ANI)
