With a name like Captain Underpants: The First Epic Movie , I think you know not to expect a serious movie. Starring the voice talents of Kevin Hart , Thomas Middleditch , Ed Helms , and Nick Kroll this animated film is bound to have bag of jokes. From Google: "George Beard and Harold Hutchins are two overly imaginative pranksters who spend hours in a treehouse creating comic books. When their mean principal threatens to separate them into different classes, the mischievous boys accidentally hypnotize him into thinking that he's a ridiculously enthusiastic, incredibly dimwitted superhero named Captain Underpants."
