#’Saved by the Bell’ trailer out for Peacock series

NBC streaming network Peacock released the first full trailer for its nostalgia-dripping “Saved by the Bell” revival, which will focus on the now grown-up kids — and their offspring — from the 1989-1993 original series.

A still-ripped-at-47 Mario Lopez returns as A.C. Slater, who is now, appropriately, a gym teacher. And, in true form, he greets annoyed former classmate Jessie Spano (Elizabeth Berkley Lauren, 48) with a barely updated, “Yo, mama. Sorry — Dr. Mama.” Some things never change, it seems.

But what has changed? The revival will follow now-California Gov. Zack Morris (Mark-Paul Gosselaar, 46), who is ensnared in political controversy about closing low-income schools and suggests sending affected students to cash-infused Bayside.

Returning original series characters also include Kelly Kapowski (Tiffani Thiessen, 46) and bushy-haired Max (Ed Alonzo, 52). New faces include Zack’s spitting-image son Mac (Mitchell Hoog, 21), Jessie’s son Jamie (Belmont Cameli) and John Michael Higgins, 57, as Mr. Toddman, the Bayside Tigers’ new principal.

But the revival will reportedly not include a cameo by 43-year-old Dustin Diamond, who portrayed Samuel “Screech” Powers in the original series and was recently rumored as having been killed in a prison riot. (Calm down: He was not.)

The new “Saved by the Bell” will premiere Nov. 25 on Peacock.
