Rob Letterman has been hired to direct a DreamWorks Animation feature based on Dav Pilkey's popular kids book series "Captain Underpants".
The story centers on two fourth graders who are best friends and who draw comics that they sell on the playground.
Their creation, Captain Underpants, becomes real when the duo accidentally hypnotize the school's mean principal who turns into an actual superhero.
Nicholas Stoller ("Forgetting Sarah Marshall," "The Muppets") penned the script, having previously worked with Letterman on "Gulliver's Travels".
The book series began in 1997 and there now more than 50 million Pilkey books in print in the U.S. alone.
