For the show's stars, it's much the same.
"Luke was a huge part of our ’90210′ family, and personally Luke was a very large part of my life. So, it’s obviously very difficult to do this without him," Jason Priestley told the Associated Press Tuesday at an event promoting the new series, titled "BH90210."
But Perry, who died in March after suffering a massive stroke, will be missing.
"It’s difficult. He was a good friend of mine,” shared Ziering.
Though Perry's tragic death rocked his former his co-stars, they've kept his memory alive on the revival's set.
"He’s been with us every step of the way," said Garth.
As for what to expect from the new series, Priestley explained it won't be a continuation of the original "90210," which ended nearly 20 years ago.
Instead, the show's stars will play comedic versions of their real selves, and their iconic "90210" characters.
“The show is comedic drama, very, very heavy on the comedy side," he explained. "It’s a scripted, fake reality show that follows Jason Priestley and Ian Ziering and Jennie Garth, all of us trying to get a reboot of ‘Beverly Hills 90210’ made, and what that entails."
“Very much like ‘Episodes.’ A little bit of ‘Arrested Development’ thrown in there. A little bit of ‘Curb Your Enthusiasm’ thrown in there. But very much in the vein of those shows," he added.
Earlier in the day, Fox released a funny new trailer for the revival featuring the show's stars hearing the "90210" theme song in the most unlikely places.
And, last week fans got to see another preview trailer of them gathering together for their first table read.
"BH90210" premieres on Wednesday, August 7, at 9 p.m. ET.
