April 18 (UPI) -- King of the Hill creators Mike Judge and Greg Daniels are set to speak on a panel at the ATX TV Festival in Autstin on May 30. The pair will be joined by showrunner Saladin K. Patterson, who also executive produced the series with Judge and Daniels, and select voice cast members including Pamela Adlon, Lauren Tom and Toby Huss. The discussion will serve as both a reunion for the series, which wrapped some 15 years ago after 13 seasons, and a preview of a reboot, which will
