Mark-Paul Gosselaar made a name for himself on the kiddie sitcom Saved by the Bell, but the 26-year-old actor, currently starring on the Dick Wolf series D.C. on the WB, is hoping audiences are ready for an older, more mature version of Zach Morris.

"I think it's time to move on from the twentysomething shows that are dealing with kids that have no idea what they want to do and aren't motivated," Gosselaar tells TV Guide Online, noting that the characters on his show are all smart and accomplished. "Sometimes I feel like people are going to look at our show and say, 'That doesn't really happen.' But anybody who lives in D.C. knows that it is possible. I would imagine the WB's audience wants something more than what they've seen. This is the next step for the network to start doing shows that are a little bit more mature."

Like Hyperion Bay? Not exactly. When asked what he learned on the failed WB series from a few seasons back, the actor diplomatically announces, "Not much. I wasn't challenged. The only thing I really learned is how the network works... how a show gets made, doesn't find an audience and fails. It was enlightening because it was the first time in my career that I experienced that. It was the first time I was actually interested in ratings."

Gosselaar is interested in the business side of things, but he has no desire to be a network executive. "I don't envy them at all," he says with a laugh. "I sometimes wonder how they're able to sleep at night making the decisions they make and hoping they're going to work. It's all too stressful for me."
