Question: is the labyrinth movie based on a book

Answer: No, Labyrinth is a 1986 musical fantasy film directed by Jim Henson, executive-produced by George Lucas, and based upon conceptual designs by Brian Froud. The film revolves around 15-year-old Sarah's (Jennifer Connelly) quest to reach the center of an enormous otherworldly maze to rescue her infant brother Toby, whom Sarah wished away to Jareth, the Goblin King (David Bowie). With the exception of Connelly and Bowie, most of the film's significant characters are played by puppets produced by Jim Henson's Creature Shop.
