4K UHD - This unhinged animated comedy is aimed at kids, but grown-ups will appreciate its manic energy and vibe too. George Beard and Harold Hutchins are a couple of middle-schoolers who live to pull practical jokes on classmates, teachers, and especially their mean principal. After a massive prank goes wrong, the principal threatens to split up the team, so they spring into action.
Beard and Hutchins hypnotize their principal into thinking he's Captain Underpants, a dumb-as-rocks comic-book hero they created. With the principal under their spell - and dressed in tighty-whities - the trio sets out to stop the real villain: Professor Pee-Pee Diarrheastein Poopypants, Esq. Professor Poopypants plans to use a gigantic toilet machine to end laughter for all time, and only Captain Underpants can stop him!
