The Walking Dead’s Glen Mazzara and Arrested Development creator Mitch Hurwitz will be speaking at NATPE, association president Rod Perth said today. The two producers will be part of the conference’s Storytellers That Shape Pop Culture series. Other speakers announced for the January 28-30 conference at the Fontainebleau Resort in Miami Beach include Electus chairman Ben Silverman, Larry King, Clear Channel Entertainment Enterprises’ president John Sykes and Frasier executive producer/creator Peter Casey. Shine America president Eden Gaha, MundoFox president Emilliano Saccone and Tele Muchen Group chairman Herbert G. Kloiber, who is NAPTE 2013 Brandon Tartikoff Legacy winner, will also be among the speakers. Mark Cuban had previously been announced as the keynote speaker for the 2013 conference, which marks NATPE’s 50th anniversary. Modern Family co-creator Steve Levitan, Cops executive producer John Langley and BET CEO Debra Lee will receive the 10th annual Brandon Tartikoff Legacy Award. Perth also said the confab has almost 300 exhibitors signed up, including every major studio. “There are 27 exhibitors brand new to NATPE,” he said on a conference call this morning. “The floor is completely sold out.” He added that the conference is up 31% in qualified buyers from last year. Perth lamented that the Realscreen conference in Washington DC is happening at the same time as NATPE. He said the same scheduling snafu will occur again in 2014 but that the two conferences hope to ensure the conflict won’t happen again.
