Get ready for a big dose of TV nostalgia when NBC's upcoming streaming service Peacock debuts later this year. On Wednesday, the Peacock Twitter account shared sneak peeks of its upcoming reboots ofSaved by the Bell, Psych andPunky Brewster. Mario Lopez and Elizabeth Berkley star in the Saved by the Bell teaser (HERE), with Lopez's A.C. Slater now grown up and working as a gym teacher at Bayside. "Remember how much fun high school used to be?" he asks Berkley's Jessie Spano, who replies, "Can you believe that was like 30 years ago?" Later, Lopez talks to two male students who got in a fight--and who turn out to be the sons of Spano and Tiffani Thiessen's character, Kelly Kapowski. Meanwhile, Soleil Moon-Frye is back as Punky Brewster (excited for this!!), while James Roday, Dulé Hill and Timothy Omundson are all back reprising their starring roles in Psych 2, which will just be a movie, not a series. Peacock is scheduled to debut in July.
