captainunderpantsDav Pilkey’s children’s book hero Captain Underpants is set to make his big screen debut courtesy of DreamWorks Animation, THR is reporting. The Muppets and Muppets Most Wanted director Nicolas Stoller is writing the screenplay, with DreamWorks Animation veteran Rob Letterman in the director’s chair. For those unfamiliar with the character, the storyline of Captain Underpants centers around “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.” The movie currently has no cast members attached, so it should come as no surprise that it’s without a release date at the moment.
