Charles Murray has stepped down as executive producer and co-showrunner on Fox’s Star, 20th TV’s midseason drama series created by Lee Daniels and Tom Donaghy.

Murray joined the project after the pilot stage in early May as part of an overall deal with 20th Century Fox TV, the studio behind Star. He served as co-showrunner on the music-themed drama alongside Donaghy under Lee Daniels Entertainment. The departure was a result of creative differences over what the show should be; there had been chatter about discord in the writers room where stories for Season 1 are being broken.

Star has not begun filming yet and for now, start of production is not expected to be delayed over the showrunner change. The hope is to get a new person in place soon, with a search currently underway.

Set in Atlanta, Star revolves around three talented young singers (Jude Demorest, Ryan Destiny and Brittany O’Grady) who navigate the cut-throat music business on their road to success. The series, whose pilot was directed by Daniels, will feature original music, along with musical fantasy sequences, as the girls dream of their future. Its cast includes Queen Latifah, Benjamin Bratt and Nicholas Gonzalez.

Daniels, Donaghy, Pamela Oas Williams and Effie Brown executive produce. Star is set to air in Empire‘s Wednesday 9 PM slot in midseason.

Before going to 20th TV, Murray was an executive producer on the first season of Netflix’s next Marvel series Luke Cage and a writer on A+E Networks’ Roots remake. He served as a writer/co-executive producer on the final two seasons of Sons Of Anarchy.

His exit from Star was first reported by TVLine.
