Rick Moranis returns as madcap inventor Wayne Szalinski in this zany kid-friendly second-sequel. This time it's the adults that get zapped to microscopic size, while the kids---believing their parents to be on vacation---throw a party. The grownups' only hope of survival (and of returning to normal size) rests on getting the kids' attention, which isn't going to be easy. Eve Gordon, Stuart Pankin, Robin Bartlett, Bug Hall, Allison Mack, Jake Richardson.
