The handsome star of the fondly remembered "Saved by the Bell" (NBC, 1989-1993) television series, Mark-Paul Gosselaar became teen celeb royalty by playing the calculating yet charming King of Bayside High, Zack Morris. After the show ended, he struggled with typecasting and inferior-quality projects like "Dead Man on Campus" (1998) before successfully reinventing himself as an in-demand adult actor, thanks to his association with Steven Bochco. Good reviews for mature turns on "NYPD Blue" (ABC, 1993-2005) and "Commander in Chief" (ABC, 2005-06) among others proved his talent could transcend his teeny-bopper history. Gosselaar enjoyed an upswing with Jimmy Fallon's successful efforts to reunite the "Bell" cast on "Late Night with Jimmy Fallon" (NBC, 2009- ) and a co-lead alongside Breckin Meyer on the legal buddy comedy, "Franklin & Bash" (USA, Network, 2011-14). While few would have predicted career longevity for any of the Bayside High grads back in the day, Gosselaar managed to enjoy a second act in his career even more successful than the first.
