Then: Zack Morris from Saved by the Bell was every teen’s mischievous crush. From breaking the fourth wall to scheming at Bayside High, Mark-Paul Gosselaar’s character became one of the decade’s most recognizable figures.

Now: Gosselaar avoided being typecast by pivoting to more serious roles, including NYPD Blue and legal dramas like Franklin & Bash. He even reprised Zack in the Saved by the Bell reboot, delighting longtime fans. While he’s not pulling the same antics as he did in high school, his steady presence on TV has kept him relevant for decades.
