"Everybody can sleep well at night," he assured reporters at the Television Critics Assocation press tour. And he's pretty confident that he won't be alone, adding that he believes co-star and on-screen love Tiffani-Amber Thiessen "has been engaged with" about returning as well.
"It looks like you will have us in some capacity," he said.
Mario Lopez and Elizabeth Berkley had already signed on to reprise their roles as A.C. Slater and Jessie Spano as series regulars for the new launch, which takes place a generation later at Bayside High.
As for Zack, even if they'd wanted to make it happen, Gosselaar wouldn't be available to appear as a regular on "Bell" because of his commitments already to freshman series "Mixed-ish."
Gosselaar's character had already been established as the governor of California, who sets things in motion by closing down low-income high schools and busing those students to higher-performing schools, like Bayside. Now, it looks like he'll get the chance to see just what that looks like in person.
Peacock picked up the show straight to series back in September, though fans are still awaiting more details about Peacock, which is set to launch in April, like just how much it's going to cost. There have been rumors of a commercial-driven format that would make it free, but NBCUniversal has not clarified anything just yet.
Details are expected when NBCUniversal presents to its investors on January 16. In the meantime, Bayside fanatics can rest easy knowing that Zack Morris will at least have some presence on the new series ... and possibly Kelly Kapowski, as well.
Josie Totah ("Champions") has been cast as the new lead of the series, the most popular girl in school, while John Michael Higgins ("Pitch Perfect") steps up as the new principal, replacing Dennis Haskins' Principal Belding.
