Writer director Taika Waititi brings his signature style of humor and pathos to his latest film, a World War II satire that follows a lonely German boy (Roman Griffin Davis), whose world view is turned upside down when he discovers his single mother (Scarlett Johansson) is hiding a young girl (Thomasin McKenzie) in her attic.

Aided only by his idiotic imaginary friend, Adolf Hitler (Taika Waititi), Jojo must confront his naive patriotism.
