“There is drama behind the scenes of Fox’s upcoming ‘Beverly Hills 90210’ revival that is worthy of — well, ‘Beverly Hills 90210,'” Variety reports. “Showrunner Patrick Sean Smith and several senior writers have quit the six-episode series, which is titled ‘BH90210.'”

The report notes that the exact reason for the “exodus” is unclear, but Variety adds: “One source said the dispute was over interference from two of the show’s lead actresses, while another noted that the writers were unhappy with one of the executives overseeing the project.”

Variety reports that Paul Sciarrotta has been named as the project’s new showrunner along with series creators Chris Alberghini and Mike Chessler.

“Sciarrotta, a member of the show’s writing staff, is currently under an overall deal with CBS Television Studios, which is producing the series,” Variety notes.

The series is scheduled to premiere Aug. 7 on Fox, with original cast members Jason Priestley, Shannen Doherty, Jennie Garth, Ian Ziering, Gabrielle Carteris, Brian Austin Green and Tori Spelling all on board.
