The best, original Scooby-Doo animated movie seen for some years, Scooby-Doo and the Goblin King is genuinely imaginative, fun, and full of surprises--particularly in its vocal casting. Besides the usual group--Casey Kasem still going strong as the voice of Shaggy (since 1969), Frank Welker as both Scooby-Doo and Mystery Inc.'s leader, Fred, Mindy Cohn as Velma and Grey DeLisle as Daphne--Goblin King features Wallace Shawn, Lauren Bacall, Tim Curry and Wayne Knight in substantial roles.
The lively story finds the Mystery Inc. gang enjoying a Halloween night at a carnival, where a hack magician (Knight) steals the power of a fairy on unauthorized leave from the spirit world. Faced with a threat to Fred, Velma, and Daphne, Shaggy and Scooby enter that parallel dimension overrun by elves, headless horsemen, witches, a talking pumpkin, etc.
Their mission is to get to the Goblin King (Curry), who can stop the magician
