Tie on that cape and pull up those tightie-whities, because word is out that DreamWorks Animation has completed a script for the bigscreen animated adaptation of the Captain Underpants book series.

Nicholas Stoller (Get Him to the Greek, The Muppets) wrote the script and Rob Letterman (Shark Tale, Monsters vs. Aliens) is set to direct. A release date has not yet been set.

Written and illustrated by Dav Pilkey, the children’s novels focus on George and Harold, two fourth graders who use hypnosis to turn their principal into their favorite comic book superhero, Captain Underpants. Since the release of the first book The Adventures of Captain Underpants in 1997, ten titles and three spin-offs have been released with several debuting at number one on the New York Times bestseller list. Captain Underpants has the added distinction of being “the most banned book in America.”
