MAGICAL MYSTERY MACHINE Sleuthing youths Gellar, Cardellini, Lillard, and Prinze get into the live action with ''Scooby-Doo''

It was also a shoot Gellar would have endured alone, had she not forced her significant other to read the script. Prinze -- who was such a fan of the cartoon he had every episode on tape and owned a Scooby bowling ball -- admits that at first he hated the idea of a live-action version. ''I didn't want to have anything to do with it,'' he says. ''But she was just like, 'Read the script, Freddie. It's a genius script [by fledgling scribe James Gunn].' I read it and laughed out loud so many times...I called my agent and went in the very next day,'' says Prinze. The couple were cast within days of each other as Daphne and Fred, joining Matthew Lillard, Prinze's frequent partner in teen high jinks, as Shaggy, and Linda Cardellini (''Freaks and Geeks'') as Velma.

''It was very attractive to us that they were a real-life couple,'' says ''Scooby'' director Raja Gosnell. ''They saw the opportunity to play an on-screen couple but without playing it really seriously or as a romantic comedy.''
