They will both star in the upcoming prequel episode, which could reportedly launch into its own spinoff series. As earlierÂ reported, ABC is in development on the prequel that would focus on Tracee Ellis Rossâ€™ character Rainbow.
Holm will play Paul, Rainbowâ€™s father, while Sumpter will play her mother, Alicia.
Other actors who are joining the episode include Arica Himmel, who will play the younger version of Rainbow, Mykal-Michelle Harris as Santamonica, Christina Anthony as Aliciaâ€™s sister, Denise, Gary Cole as Paulâ€™s father, Harrison, and Ethan William Childress as Johan.
The episode could potentially serve as a backdoor pilot for the prequel, which would be the second spinoff of â€œBlack-ishâ€ to date.Â â€œGrown-ish,â€ which was recently renewed for a third seasonÂ at Freeform features Johnson daughter Zoey (Yara Shahidi) in college and ranks at the top comedy among women 18-49 and females 12-34.
â€œBlack-ishâ€ creator Kenya Barris recently departed his overall deal atÂ ABCÂ Studios for a new pact at Netflix.Â Barrisâ€™ relationship with ABC began to show signs of strain last March whenÂ VarietyÂ reported that the network had indefinitely shelved an episode of â€œBlack-ishâ€ that he wrote and directed, titled â€œPlease, Baby, Please,â€ which touched on current events, including controversy over athletes kneeling during performances of the national anthem.
