If you spend your time solving ghostly mysteries, you'd think the last person you want on your team is the gal from ''Clueless.'' Nonetheless, Variety reports, Alicia Silverstone is joining the cast of ''Scooby-Doo 2'' Then again, she does have some sleuthing experience from her Batgirl role in ''Batman & Robin'' -- not to mention time logged in a creepy cave.
In the sequel, which began shooting last week in Vancouver, the Scooby gang (returning cast members Sarah Michelle Gellar, Freddie Prinze Jr., Matthew Lillard, and Linda Cardellini) must foil a villain who has a machine that creates baddies familiar from the animated series, including the Creeper, Captain Cutler, and the 10,000-Volt Ghost. Silverstone will play Heather, a dogged reporter with ties to Patrick (Seth Green), the mysterious curator of the Coolsonian Criminology Museum. No word on whether she'll get the scoop on what Scooby Snacks are really made of; let's hope for the vegan actress' sake that they're meat-free.
Silverstone, who seemed to have fallen off the radar after costarring in Kenneth Branagh's 2000 musical version of ''Love's Labour's Lost,'' spent much of 2002 in ''The Graduate'' on Broadway, opposite Jason Biggs and Kathleen Turner. She's also the star of a prospective fall series for NBC, a comedy/drama from Darren Star (''Sex and the City'') called ''Miss/Match,'' based on the experiences of a real-life New York divorce lawyer who doubles as a matchmaker.
