Never thought I’d be so darn excited to see a "Scooby Doo" movie [must be the drugs], but my dear, dear Alicia Silverstone has changed all that. The "Clueless" cum dissapearing act has joined the cast of the sequel, according to a report on Zap2It. Silverstone will play Heather, a relentless reporter who is aided by museum curator Patrick (Green). The film, penned by James Gunn, started shooting last week in Vancouver and will be released on March 26, 2004. Now here’s hoping "we" get an invite to visit the set this time round. Listening WB?
