After 11 years off network television, and bolstered by DVD sales of a series of DTV movies and the fact that reruns of earlier series were generating big ratings for Cartoon Network, Scooby-Doo made a triumphant return with What's New Scooby-Doo?, airing on Kids' WB!.
The series came 3 months after the first live-action feature film, and retained one disturbing element. Team co-leader Fred Jones (Frank Welker) was now more of a geek who marked out over certain things. The producers even paid homage to the 1972-4 New Scooby-Doo Movies by inserting guest stars when needed, such as baseball star Mike Piazza, and musicians Lindsay Pagano and Simple Plan, the latter of whom also performed the show's theme song.
The traditional format was eschewed occasionally in favor of a more traditional whodunit, which actually was a welcome relief, considering the fake monster/ghost of the week had long become cliched. By switching to a whodunit from time to time, it allowed the gang to prove they didn't need to confine themselves to debunking phony spooks all the time. Unfortunately, the whodunits came too few and too far between.
There were casting changes. With Don Messick, the original voice of Scooby, having passed on 5 years earlier, and with 2 actors having been tried in the interim, including Neil Fanning in the movie earlier in 2002, Frank Welker added to his considerable workload by essaying the dual roles of Scooby & Fred, and received star billing, along with the returning Casey Kasem (Shaggy). Also, former sitcom star Mindy Cohn (ex-The Facts of Life) came out of retirement to play Velma, and Grey DeLisle was cast as Daphne, but that change had taken effect a year earlier in "Scooby-Doo & The Cyber Chase", after her predecessor, Mary Kay Bergman, had passed away. Of course, the biggest reason why Welker & Kasem were accorded star treatment is they were the only original cast members left from the original Scooby-Doo series back in 1969.
Here's the intro:
The downside to the show airing on Kids' WB! was the fact it was pulled periodically so that the network could play extra episodes of anime such as Yu-Gi-Oh!, which was played into the ground to begin with. The constant tinkering with the lineup resulted in the series being cancelled in February 2005, more than halfway through the 3rd season. Reruns are airing this month on Boomerang.
