Mark-Paul Gosselaar spent the first season of the NBC procedural drama “Found” as both a captor and captive. His character – known only as Sir – was shown in the past where he was holding a young Gabi Mosely as a prisoner. This was mixed with the present where an adult Mosely (Shanola Hampton) is holding Sir captive and using his warped knowledge to help her solve missing person cases. She is a public relations specialist who with her crisis management team now makes sure there is always someone looking out for the forgotten missing people. The secret she had been hiding changes when Sir escapes and vows to destroy Mosley’s life. The third season is scheduled to begin at 10 p.m. Oct. 3 on KGET. “Found” deals with the very serious situation of missing people. In any given year, more than 600,000 people are reported missing in the U.S. and more than half that number are people of color that the country seems to forget about. Gosselaar had not been told when he signed on to “Found” that a second season would have him again being a hunter. He admits that he agreed to the role so quickly there wasn’t much time or need for explanations. The change didn’t bother Gosselaar because he had great faith that series creator Nkechi Okoro Carroll and her team would provide him with plenty of room to be creative. He got that creativity without it ever feeling forced. “Every script that we got, I remember I kept calling you [Carroll] saying how can we continue this trajectory because it just continues to rise right from the start of the second season,” Gosselaar says. “So, there is this level of trust that you have to give to your showrunner and the team.  Sometimes it works.  It's a gamble, and sometimes it doesn't. “I'm very, very, very pleased, very excited for our fans and our audience to watch the second season because everything that we built up in the first season, there is going to be a payoff. If you've put the time into our show, a lot of the times I feel like shows find themselves in a position where it's hard to maintain, but I feel like we've maintained and excelled from where we were last season.” Carroll sits down with members of her cast at the start of every season where she tells them in broad terms how the arc of the season will go. It is a way to let them know if something strange pops up in a script that is a way of planting a seed for an episode in the future. The meetings are important because Carroll is certain actors can do their jobs better if they have at least a rough understanding of where their character is headed. If a major shift is looming, Carroll calls the actor to let them know what to expect. Carroll says, “I'm a big fan of overcommunication with our talent when it comes to stuff like that, so that everyone can do their jobs. At the start of every season, I sort of have a 15-page document I give my writers room that talks about every character's north star, the big sort of pillars we're going to hit on our way there. “I tell them I'm so not the smartest person in the room, so please find me a better journey to this north star, and they come in and kill it.” Gosselaar jokes that he was very content with being a prisoner in the basement because that meant he only needed to work one or two days a week. He’s jokingly concerned that having Sir in the world will mean more work on his part and that he will have to learn the names of his fellow actors. As a reminder, the cast of “Found” also includes Kelli Williams, Brett Dalton, Gabrielle Walsh, Arlen Escarpeta and Karan Oberoi. Playing such a vile character is far from the norm for Gosselaar who launched his career on the popular teen sitcom “Saved By the Bell.” Since then, his credits have included “Will Trent,” “NYPD Blue,” “Raising the Bar,” “Franklin & Bash,” “The Passage,” “Pitch,” “Commander in Chief” and “Mixed-ish.” Gosselaar wasn’t looking for a role that would be a contrast to his past roles when “Found” came along. He wanted to play the role because he found the script to be so solid. There’s also the matter that Gosselaar simply enjoys acting. “I really like working.  I mean, honestly, when I look at something, I think is this something that I want to be on for five, six, seven, eight years.  And we talked about this.  I mean I hope I'm on this until we're in the ‘SVU’ world.  Nothing would make me happier,” Gosselaar says. “So, again, it's a gamble, what we do as actors when you're given a script.  And to me, this was one of the brightest scripts of that year.”
