Scooby-Doo and the Goblin King (2008)

In this adventure led by Shaggy and Scooby Doo, the future of their friends depends on them stopping the Amazing Krudsky from turning everyone into Halloween monsters after he steals Princess Fairy Willon's magic lantern. This amusing film revisits a premise shared by other classic films of the same cartoon, dating back to the 1980s, and was the first to be produced entirely without the original creators, Bill Hanna and Joseph Barbera.
