The Supremes At Earl’s All-You-Can-Eat has found its cast in Uzo Aduba, Sanaa Lathan and Aunjanue Ellis.

Per Deadline, they will star as the three main characters the Searchlight adaptation of Edward Kelsey Moore’s 2013 eponymous debut novel. Like the book, the film will follow three friends who have the group nickname “The Supremes.” These friends have gone through the ups and downs of life, but after everything they’ve been through, their friendship has now come to its greatest test.

More context for 'The Supremes At Earl's All-You-Can-Eat' gives a closer look at what fans can expect from the film.

The three friends, Odette, Clarice and Barbara Jean, are described as “remarkably resilient,” according to Penguin Random House. The story moves back and forth between the present and the past, showcasing more about The Supremes’ bond and their weekly catch-up sessions at their local diner, owned by Earl.

Earl’s diner “represents community for these women, a meeting place that holds their lives together and offers solace, good humor, and support when it is most needed.”

The description also gives a look at some secondary characters we might see in the film.

Earl, of course, is a definite, but other characters in the book include Minnie, the town’s fake fortune-teller; Veronica, Clarice’s self-involved cousin; Sharon, Veronica’s daughter who can’t get enough of doughnuts and Richmond, Clarice’s womanizing husband who had a career as a football star.

Other secondary characters include Lester, Barbara Jean’s late husband, whose death has led Barbara Jean to find solace in alcohol. Barbara Jean’s alcoholism is also affected by her son Adam, who was killed by her former lover’s racist brother.

Gina Prince-Bythewood wrote the script with revisions by Tina Mabry.

Mabry will also direct with Temple Hill and Searchlight Pictures producing.
