According to sources, the untitled project is an hour-long mockumentary-style dramedy that would find former 90210 cast members Jennie Garth, Jason Priestley, Tori Spelling, Ian Ziering, Brian Austin Green and Gabrielle Carteris playing themselves — albeit in a somewhat heightened state. The potential series — which was first rumored last March — would chronicle the gang’s efforts to get (another) 90210 revival off the ground.

It’s official — Fox has closed a deal for the new series reuniting original Beverly Hills, 90210 cast members Jason Priestley, Jennie Garth, Ian Ziering, Gabrielle Carteris, Brian Austin Green and Tori Spelling. Titled 90210, the show, from CBS TV Studios, has received a six-episode order to air this summer.

Fox, which aired the original Beverly Hills, 90210 series, had emerged as the frontrunner for the new 90210, which was taken out in December. The broadcast network was described as being “the most passionate” about the project, a serialized drama – with a dose of irreverence — inspired by the sextet’s real lives and relationships, in which Priestley, Garth, Ziering, Carteris, Green and Spelling will play heightened versions of themselves.

“Beverly Hills, 90210 left an indelible impact on pop culture and an entire generation,” said Fox Entertainment president Michael Thorn. “Its powerful legacy is an important part of our network’s DNA – bold stories not told anywhere else and bigger-than-life-characters – and we’re honored to bring back the beloved original cast members for 90210.”

Last month, Fox Entertainment CEO Charlie Collier told Deadline that 90210 and Melrose Place are among his favorite Fox series of all time and pieces of IP he would like to explore at the network.

In the new series, having gone their separate ways since the original series ended 19 years ago, 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. 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?

The series was conceived by Mike Chessler and Chris Alberghini, who worked on the CW’s 90210 reboot and on Spelling’s series So Notorious, along with with Spelling and Garth.

Alberghini and Chessler will write the series. They executive produce with Carteris, Garth, Green, Priestley, Spelling and Ziering. CBS TV Studios-based Ghen Maynard, who has a relationship with Spelling and Garth, developed the project.

Beverly Hills, 90210 premiered on Fox on October 4, 1990, when it became an instant pop culture sensation and one of the most popular programs in the network’s history. Centered on the tony Los Angeles community identified in its title, the show aired for 10 seasons, during which it documented the trials and tribulations of a group of friends from high school to college and into early adulthood, as they navigate a myriad of coming-of-age dramas and complex rivalries.

Coincidentally, 90210 alumna Tori Spelling is one of the celebrities on Fox’s breakout reality competition The Masked Singer.

“It’s not technically a reboot, because I feel like everyone has seen the reboot. We don’t want to be the last ones like doing the reboot thing, and no one wants to see like old versions of ourselves, but they do want to see us playing our characters, so what we’re doing is the entire cast is playing heightened versions of themselves,” Spelling said of 90210 in one of the interviews after her exit from The Masked Singer. “Think Curb Your Enthusiasm episodes, in an hourlong show, and we’re all playing heightened versions, so it could be fictional, it could be non-fictional, people will have to guess. And then we will have pop-ins, because we’re behind the scenes trying to do the reboot.”
