20th Century Fox Animation is to adapt William Joyce's illustrated children's book
The Leaf Men and the Brave Good Bugs, says the Hollywood Reporter.
The feature, which will see Oscar winner Chris Wedge direct, is described as an epic adventure centering on ancient elfin magic.
The book follows a troop of brave bugs who march off to save a garden, where they encounter an evil spider queen and must summon the mythical Leaf Men to save the day.
