When the Potter family moved into their new San Francisco apartment, they had no idea the building was a gateway into a dimension inhabited by elves, goblins, and other magical beings. Aided by a kindly witch, young Harry Potter (!) must stop the evil Troll King, who's taken his sister's form, from changing everyone in the building and merging the two realms. The fantasy/adventure "Troll" stars Noah Hathaway, Michael Moriarty, June Lockhart, and Sonny Bono. Two-disc set also includes "Troll 2" and the documentary "Best Worst Movie."
