Mark-Paul Gosselaar won everyone's hearts as Zack Morris in "Saved By the Bell."
Gosselaar's beloved role on "Saved By the Bell" has had many reprisals: in two TV movies, two spin-off shows, and with Jimmy Fallon on late night TV, to be precise.
Since then, he's appeared in a number of television roles, most notably as Detective John Clark in "NYPD Blue," and as an FBI agent on the Fox series "The Passage."
