Calling all preppies! After years of delays and rumors, the new, refreshed, and revamped Saved by the Bell is really happening. The sequel, which will feature Mario Lopez and Elizabeth Berkley reprising their roles as A.C. Slater and Jessie Spano, is headed to Peacock, the new NBCU-owned streaming service launching in spring 2020. Of course, a project this big and — hello! — exciting will undergo some big changes and tweaks before it sees the light of day. Here's everything we know about the revival of the classic NBC high school sitcom, which ran from 1989 to 1993 before spawning two spin-offs and a pair of TV movies.

Zack is now the Governor of California: In the updated Saved by the Bell, Zack Morris (Mark-Paul Gosselaar) is a major politician, but he's in for a crisis after "closing too many low-income high schools." To clean it up, Governor Morris decides to send a bunch of students to the highest-performing schools in the state — including Bayside High — and the new students give the privileged Bayside students a much-needed and hilarious reality check.

Although Gosselaar, who currently stars on ABC's Mixed-ish, previously indicated that he hadn't been contacted about returning to the role, he later confirmed that he would indeed appear in a few episodes of the revival.

You'll see faces you recognize: As previously mentioned, Elizabeth Berkley and Mario Lopez are reprising their roles as Jessie Spano and A. C. Slater — the "It" couple at Bayside High for much of the show's run. There's no word yet on whether other series regulars like Tiffani Thiessen, Dustin Diamond, Lark Voorhies, or Dennis Haskins will return, but Lopez's behind-the-scenes video from the set proves that the series will welcome back Ed Alonzo as the hip diner's owner, Max.

There will be a ton of new faces: Given the updated plot, which involves an influx of new students, the sequel series is set to welcome plenty of newcomers to the franchise. In January, Peacock announced the comedy had found its first new lead in Champions alum Josie Totah, who will play the sharp-tongued cheerleader Lexie.

The tone might be a little different... and fresh: Tracey Wigfield, who worked on 30 Rock and created Great News, has been tapped to provide a new take on show, so it's not hard to imagine SBTB to having at least some of the wacky and wild feeling of those zany comedies. Original producers Peter Engel and Franco Bario will both serve as executive producers too.

Saved By the Bell is available to stream on Hulu.
