If you close your eyes and think of the 1990s, you probably see a giant brick cellphone and a head of perfectly bleached blonde hair. That hair belonged to Zack Morris, the fast-talking, fourth-wall-breaking schemer who ran Bayside High like a mini-dictator with a heart of gold. But behind the oversized sweaters and the ability to "time out" reality was a real person.
Mark-Paul Gosselaar is the man who plays Zack Morris.
Most people know the name. Some can even spell it correctly on the first try. Yet, there is a weird disconnect between the actor and the character that has persisted for over thirty years. Gosselaar didn't just play Zack; he inhabited a role that became a cultural blueprint for the "lovable jerk" trope. He’s been playing him, on and off, since 1988. That is a long time to be associated with a guy who once sold his friends’ secrets for a quick buck.

The Face Behind the Phone: Who Plays Zack Morris?
It started with a show called Good Morning, Miss Bliss.
Before the Max and the beach club, Zack Morris was just a kid in Indiana. The show was technically a Disney Channel vehicle for Hayley Mills, but the blonde kid with the smirk stole the spotlight. When that show flopped, NBC took the best parts—Gosselaar, Dustin Diamond (Screech), and Lark Voorhees (Lisa)—and moved them to California.
Suddenly, Mark-Paul Gosselaar was the biggest teen idol on the planet.
He was only fourteen when he started. By the time Saved by the Bell hit its stride, he was a household name. But here’s the kicker: Gosselaar isn’t actually blonde. He spent years in a salon chair having his hair chemically lifted to that signature "Zack Morris Gold." It was a literal transformation that defined his physical identity for the better part of a decade.
More Than Just Bayside
If you think Gosselaar disappeared after the Wedding in Las Vegas movie, you haven't been paying attention. He’s one of the few child stars who managed to build a "serious" adult career without a public meltdown. It wasn't easy. He spent years trying to shake the "Preppy" label.
- NYPD Blue: He shocked everyone by joining this gritty drama as Detective John Clark Jr. He was replacing Rick Schroder, another former child star. It worked. He proved he could do more than just wink at a camera.
- Franklin & Bash: This was a return to his charismatic roots. Playing Peter Bash, he was basically Zack Morris with a law degree and less hair gel.
- Pitch: A short-lived but critically adored show where he played a veteran catcher. He grew a massive beard and gained weight. You could barely recognize him.
- Found: His most recent turn as "Sir," a kidnapper. It’s dark. It’s twisted. It is the polar opposite of the guy who used to hang out with Mr. Belding.
The 2020 Revival and "Governor" Morris
When Peacock announced they were bringing back Saved by the Bell in 2020, everyone asked the same thing: Is the original guy coming back?
Yes. Mark-Paul Gosselaar returned, but with a twist.
In the revival, Zack Morris is the Governor of California. Honestly, it’s the most logical progression for a character whose primary skill was manipulation. He’s a recurring character this time around, playing the father to a new Bayside student, Mac Morris (played by Mitchell Hoog).
Watching Gosselaar play an older, slightly more oblivious version of Zack was a trip. He managed to capture that same "effervescent" quality—the ability to say something objectively terrible and make you smile anyway. Gosselaar himself has admitted in interviews that Zack is a bit of a "douche," but he plays him with such charm that we keep coming back.
The "Zack Morris is Trash" Phenomenon
You can't talk about who plays Zack Morris without mentioning how the internet re-evaluated the character. A few years ago, a series called Zack Morris is Trash went viral. It pointed out that Zack was actually a pretty horrible friend. He gaslit Kelly, exploited Screech, and generally caused chaos.
Gosselaar has been a surprisingly good sport about this.

He even started a podcast called Zack to the Future where he rewatched the episodes for the first time. Hearing the man who plays Zack Morris cringe at his own character’s behavior is peak entertainment. He’s very aware of the legacy. He knows that to a certain generation, he will always be the kid with the "Time Out" powers.
Why the Casting Mattered
Could anyone else have played him? Probably not.
There’s a specific brand of 90s charisma that Gosselaar possessed. It was a mix of California cool and theater-kid energy. If the actor had been even 10% less likable, Zack Morris would have been the villain of the show. Instead, he became the hero.
Gosselaar’s Dutch-Indonesian heritage (his mother is from Indonesia, his father from the Netherlands) gave him a unique look that the cameras loved. He was the "All-American" boy who wasn't actually the typical Hollywood mold.
Next Steps for the Savvy Fan
If you want to see the full range of the man who plays Zack Morris, skip the Bayside reruns for a night. Fire up a few episodes of Found on Peacock or NBC. Seeing him go from the ultimate teen heartthrob to a terrifying, bearded antagonist is the best way to appreciate what a "journeyman" actor really looks like. Or, if you're feeling nostalgic, track down his appearance on The Tonight Show Starring Jimmy Fallon from 2009—he showed up in full Zack Morris costume, wig and all, and stayed in character the entire time. It’s a masterclass in embracing your past while moving forward.
Check his recent credits on IMDb to see what’s currently filming, as he’s rarely out of work for more than a month or two. He’s proven that while Zack Morris might be his most famous role, Mark-Paul Gosselaar is the one with the real staying power.
