Hey, if "The Simpsons" can hang around forever…

It looks like there’s another television show that is going to outlive all of us…

Scooby-Doo, a program that been around in one form or another since 1969, is spurning a live-action movie for Cartoon Network that’s being billed as a prequel to the two-live action movies. Titled Scooby-Doo: In The Beginning, it details how the Mystery, Inc. gang met.

The new movie is premiering in 2009 with a DVD release scheduled simultaneously.

Highland Park (IL)-native and former Happy Days writer Brian Levant is directing the made-for-TV flick. However, don’t look for Freddie Prinze Jr. and Sarah Michelle Gellar to reprise their roles. Instead, a new cast is filling the roles for Fred, Velma, Daphne, and Shaggy. Like the previous movies, Scooby is being CGI animated, and is being voiced by longtime voice-over artist Frank Welker (who voiced Fred in the original animated series.)

Meanwhile, a new animated made-for-video movie (Scooby Doo and the Goblin King) hits store shelves next month.

But don’t look for new episodes of Scooby-Doo’s latest incarnation.

After two ratings-challenged seasons, Shaggy & Scooby-Doo Get A Clue (featuring only Shaggy and Scooby-Doo) has been canceled, swept out along with the rest of the Saturday Morning schedule at The CW, replaced by a lineup programmed by 4KidsTV. Shaggy & Scooby was dropped from the lineup in March, and hasn’t returned.

The series broke Shaggy and Scooby out of character (they’re usually broke and starving cowards), and the audience wouldn’t accept them as brave millionaires. More interesting, the voice of Shaggy (American Top 40’s Casey Kasem) was done instead by Scott Menville and Kasem was regulated to a seldom-seen second character, but he did voice Shaggy in the last direct-to-video movie (2007’s Chill-Out Scooby-Doo.)
