The classic Jay Ward cartoon "Peabody's Improbable History" (featured on the old "Rocky & Bullwinkle Show") gets its own CGI spin-off. Ty Burrell (from "Modern Family") voices the brilliant canine inventor while Max Charles (from "The Neighbors") voices his nerdy adopted son. In order to impress a neighbor girl, Sherman "borrows" dad's time machine and accidentally unleashes chaos throughout history. Leonardo da Vinci, Mona Lisa, Albert Einstein and Agamemnon drop by, giving guest stars Lake Bell, Stanley Tucci, Mel Brooks and Patrick Warburton something to do. 91 minutes PG.
