The cast members of «Saved by the Bell» are some of the most recognizable figures in television history. The beloved show, which aired from 1989 to 1993, provided audiences with a glimpse into the amusing escapades at Bayside High School, creating enduring memories for all who tuned in during its run.

«Saved by the Bell» was not only uproariously funny but also addressed serious topics on occasion, including drug use, homelessness, women’s rights, and the perils of driving under the influence.

What’s more, the show’s lead actors and actresses quickly soared to stardom, transitioning from relative obscurity to widespread popularity. Among all the beloved characters, Zack Morris undoubtedly held a special place in our hearts.

That’s why it’s such a surprise to witness the transformation of the actor who portrayed him, Mark-Paul Gosselaar. At 49 years old today, Gosselaar has gone through quite the change.

Mark-Paul Gosselaar may not be a household name, but Zack Morris certainly is. The charming and mischievous Zack was arguably the central character of «Saved by the Bell» and one of the most beloved.

In simple terms, he was the epitome of what every young boy aspired to be. Witty, daring, full of pranks, yet capable of winning over teachers and the school principal to always escape unscathed.

Mark-Paul Gosselaar brought Zack to life, winning the hearts of audiences and fellow cast members. He could be considered one of the most popular teenage TV actors of his time, defined by his youthful good looks and cheeky grin.

Fans were taken aback when Gosselaar made an unexpected appearance at the 90s Con festival, according to the Daily Mirror. The actor, whose post-«Saved by the Bell» work includes roles in shows like «CSI,» «Raising the Bar,» and «The Passage,» attended the event in a cream button-down shirt and gray trousers.

Other guests at the event included Melissa Joan Hart from «Sabrina the Teenage Witch» and the cast of «Charmed.» Mario Lopez, who starred alongside Gosselaar in «Saved by the Bell,» also made an appearance.

Everyone has grown up and looks remarkably different. If you were to encounter them on the street, you might not even recognize them!

Wow! It’s hard to say what was expected, but Gosselaar certainly looks different from his days as Zack. Understandable, given that 30 years have passed!
