Grey’s Anatomy star Jesse Williams is set to make his directorial debut with Till, a film about Mamie Mobley Till, the mother of Emmett Till, a Black teen who was killed for allegedly catcalling a White woman in Mississippi in 1955.

According to Deadline, the screenplay is by Michael Reilly and civil rights filmmaker Keith A. Beauchamp. The drama focuses on Mamie’s quest for justice following the death of her 14-year-old son, which is based on Beauchamp’s documentary, The Untold Story of Emmett Louis Till.

The project will be produced by Williams, Barbara Broccoli, Thomas Levine, Beauchamp, Leah Natasha Thomas and Whoopi Goldberg, who will also appear in the film.

“I’m honored to be directing the story of Mamie & Emmett: a tale of revolutionary defiance in the face of tremendous personal and public devastation,” the actor told Deadline. “An exploration of power and pulling back the curtain on cultural violence; of boyhood and maternity challenging America’s reflex to hide from itself; underdogs refusing to pretend that terror is freedom.”

Till is scheduled for production beginning in summer 2019.
