Tina Mabry and Gina Prince-Bythewood have booked a helluva cast for their “The Supremes at Earl’s All-You-Can-Eat” adaptation at Searchlight Pictures. Uzo Aduba, Sanaa Lathan, and Aunjanue Ellis will portray the titular Supremes, a close-knit friendship trio, Deadline announced. Mabry is directing the film and did some revisions to Prince-Bythewood’s original script.

Based on Edward Kelsey Moore’s 2013 bestseller, “The Supremes at Earl’s All-You-Can-Eat” is about “three best friends dubbed ‘The Supremes,’ who have weathered life’s storms together for two generations through marriage and children, happiness and the blues,” per the source. The women “find their paths at a crossroads that test their lifelong bond.”

“Love & Basketball” collaborators Lathan and Prince-Bythewood will both be attending TIFF this year. The former is premiering her feature directorial debut, “On the Come Up,” and the latter is bringing her latest, Viola Davis-starrer “The Woman King.” Lathan is up for an Emmy for her guest spot on “Succession,” and Prince-Bythewood most recently helmed an episode of “Women of the Movement.”

Aduba is among the voice cast of the animated “Lightyear,” which is now in theaters. A five-time Emmy nominee and three-time winner, she has won statuettes for “Orange Is the New Black” and “Mrs. America.” Ellis received an Oscar nod this year for her supporting turn in “King Richard.” She previously netted Emmy noms for “Lovecraft Country” and “When They See Us.”

Mabry made her feature debut with 2009’s “Mississippi Damned.” Also a frequent TV helmer, she counts “Women of the Movement,” “Pose,” and “Insecure” among her credits. She won a DGA Award and an NAACP Award for Amazon’s “American Girl” special “Melody 1963: Love Has to Win,” which she produced and directed.
