This is a movie mostly for the kids. It is done well, but there is little here to appeal to adults.
Leonard Maltin/Plot synopsis:
Petersen's first English-language film is magical, timeless fantasy built around young Oliver visualizing what he's reading from a mystical book: boy warrior Hathaway is the only hope of saving the empire of Fantasia from being swallowed up by The Nothing. Amazing, unique effects, characters, and visual design (and a not-so-subtle message that Reading Is Good). Followed by two live-action sequels, and an animated TV movie and series. Technovision.
