It is produced by Warner Bros. Animation and shown as a modernized approach of the original series. The voice cast from the 2002-2006 series What's New, Scooby-Doo? reunites for the new series, with the exception of Matthew Lillard (who appeared in the first two live-action Scooby-Doo movies) replacing Casey Kasem (due to the latter's retirement). Casey Kasem still remains on the show but portrays Shaggy's father, Colton. The series premiered on Cartoon Network in April 5th, 2010.
