Brian Levant ("The Flintstones in Viva Rock Vegas," "Are We There Yet?") has signed to direct a TV movie prequel to the "Scooby Doo" movies.

A nation-wide casting call is now underway to find the new Fred, Daphne, Velma and Shaggy according to Moviehole.

Daphne's a mystery writer, Fred's a football player, Shaggy is a school dropout; and Velma is a teen U.S ambassador for World Hunger.

All four apply for jobs at the school paper and end up solving their first mystery together. Production begins in August in Vancouver.
