AceShowbiz - "BH90210" has yet to arrive on FOX, but it seems like the drama has already occured behind-the-scenes. A new report suggests that showrunner Patrick Sean Smith and several senior writers have quit the "Beverly Hills 90210" revival.

According to Variety, the real reason of the crew shake-up is currently unclear. A source claims that there's a dispute over interference from two of the show's lead actresses. Meanwhile, another insider says the writers are unhappy with one of the executives overseeing the project.

The report further reveals that Paul Sciarrotta has been tapped to be the new showrunner for the reboot. He will join series creators Chris Alberghini and Mike Chessler. In addition to being a member of the show's writing staff, Sciarrotta is attached as the producer.

The new iteration of "Beverly Hills, 90210" was announced back in February. Starring original stars Tori Spelling, Shannen Doherty, Jason Priestley, Jennie Garth, Brian Austin Green and Ian Ziering among others, the series will see them playing "heightened versions of themselves in a brand-new serialized drama -- with a healthy dose of irreverence -- that is inspired by their real lives and relationships."

"Having gone their separate ways since the original series ended 19 years ago, Shannen, Jason, Jennie, Ian, Gabrielle, Brian and Tori reunite when one of them suggests it's time to get a 'Beverly Hills, 90210' reboot up and running. But getting it going may make for an even more delicious soap than the reboot itself," the official logline of "BH90210" states.

"What will happen when first loves, old romances, friends and frenemies come back together, as this iconic cast -- whom the whole world watched grow up together -- attempts to continue from where they left off?" it continues.

"BH90210" is set to premiere on August 7 on FOX.
