Disney’s follow-up to 2019’s The Lion King, which will be a prequel, is putting together its cast.

Actors Kelvin Harrison Jr. (Waves, Luce) and Aaron Pierre (The Underground Railroad) will lead the cast of the Barry Jenkins-directed film. Pierre is voicing Mufasa and and Harrison Jr. will play Taka aka Scar.

Per Deadline‘s exclusive report, the film “will explore the mythology of the iconic characters, including Mufasa’s origin story.”

The report states that “additional casting is in process with plenty of big names likely.”

The untitled film will implement the same animation technology used by Jon Favreau in the 2019 film. Jeff Nathanson, the writer of the 2019 film, is back for this one as well.

Pierre was also seen recently in Universal’s Old. Harrison Jr., who always has a stacked slate, is wrapped on Joe Wright’s Cyrano and Baz Luhrmann’s Elvis Presley film.

This project keeps Jenkins at Disney, where he has an Alvin Ailey biopic in development. He is coming off of his acclaimed Amazon series, The Underground Railroad. He also wrote the script for the Ryan Destiny-starrer Flint Strong and is working on an adaptation of the documentary Virunga at Netflix.

“Helping my sister raise two young boys during the ’90s, I grew up with these characters,” Jenkins said in a prior statement to Deadline. “Having the opportunity to work with Disney on expanding this magnificent tale of friendship, love and legacy while furthering my work chronicling the lives and souls of folk within the African diaspora is a dream come true.”
