Jojo Rabbit is a war comedy-drama film written and directed by Taika Waititi, adapted from Christine Leunens's 2008 book Caging Skies. Roman Griffin Davis portrays the title character, Johannes "Jojo" Betzler, a ten-year-old Hitler Youth member who finds out that his mother is hiding a Jewish girl in their attic. He must then question his beliefs while dealing with the intervention of his imaginary friend, a fanciful version of Adolf Hitler with a comedic stance on the politics of the war. The film also stars Sam Rockwell, Rebel Wilson, Stephen Merchant, and Alfie Allen.
