SEE IT: Emmett Till film trailer released on what would’ve been his 81st birthday

On what would’ve been the 81st birthday of Emmett Till, the first official trailer for the forthcoming movie about his mother’s push for justice has been released.

“Till,” directed by Chinonye Chukwu, chronicles the story of Mamie Till-Mobley, who became a civil rights movement figure after her 14-year-old son was lynched in Mississippi in 1955, following false accusations from a white woman.

“The lynching of my son has shown me that what happens to any of us, anywhere in the world, had better be the business of us all,” the mourning matriarch, played by Danielle Deadwyler, says in the 2½-minute clip released on Monday.

Deadwyler gained notoriety starring as treacherous hood rat LaQuita “Quita” Maxwell in the sudsy Oprah Winfrey Network primetime drama, “The Haves and the Have Nots” from 2015 to 2017. The Atlanta native also starred in “The Harder They Fall,” alongside Idris Elba, Regina King and Jonathan Majors.

“Till” also stars “All American” actor Jalyn Hall as Emmett, and Whoopi Goldberg as Emmett’s grandmother, Alma Carthan.

Veteran actor Frankie Faison, Haley Bennett, Sean Patrick Thomas and Tony Award nominee John Douglas Thompson round out the cast.

“This is a story that people think they know…but people forget that these are two people, a mother and a son. And in the middle of all this nation could throw at two people, and threw at them, Mamie threw it back ... it’s a mother’s story,” Goldberg — who serves as an executive producer of the film — said on “Good Morning America.”

The world premiere of “Till” will take place at the 60th New York Film Festival before arriving in select theaters on Oct. 14 and a wider release Oct. 28.
