Zoinks! Gellar, Prinze May Do \”Scooby\”. Sarah Gellar and Freddie Jr. might star in a live-action Scooby Doo movie. You just know that\’s going to suck. I hope they get Rob Lowe to be Shaggy though, when he was on Saturday Night Live a few months ago he did a dead-on impression. Like, zoinks, maaan.
