This delightfully silly animated caper, based on the books by Dav Pilkey, centres on best buds and elementary school pranksters George (superstar stand-up Kevin Hart) and Harold (Silicon Valley's Thomas Middleditch). To begin with the titular character exists solely within the pages of the pair's self-penned comic-book series, but all that changes after a mishap involving a surprisingly effective cereal box prize. Mean-spirited principal Mr Krupp (Ed Helms) is somehow transformed into a real-life Captain Underpants, the Y-fronted and spectacularly stupid superhero soon to do battle with deranged scientist Professor Pee-Pee Poopypants (Nick Kroll) and his giant robotic toilet monster. Turbo's David Soren directs.
