In 2017, Kroll then had a second villain voice role as a villainous mad scientist Professor Poopypants in the DreamWorks animated superhero film Captain Underpants: The First Epic Movie. Although many critics only either mentioned his character in passing, some pointing out his similarities with Albert Einstein,^[17][18][19] or his "committed" performance,^[20][21] Matt Zoller Seitz took particular note of his performance, praising it as "irrepressibly silly" with "an orange juice spit-take voice". Seitz further stated that "[t]he way Kroll savors every syllable of his alternately peevish, self-pitying and nonsensical dialogue—aided mightily by the animators, who've given the character a fireplug body and a waddling walk—transforms the ridiculous into the sublime."^[22] In recent years, Kroll has taken several non-comedic acting roles, such as that of Bernie Cohen in Loving and Rafi Eitan in Operation Finale, both historical drama films.^{[citation needed]}

Book
