April 24 (UPI) -- Sam Rockwell has been cast in the next film from director Taika Waititi, a World War II film titled Jojo Rabbit that stars Scarlett Johansson.
Jojo Rabbit will follow a young German boy in Hitler's army who finds out that his mother, played by Johansson, is hiding a Jewish girl inside their home.
Rockwell will appear in the film as a Nazi captain who runs a Hitler Youth camp, noted The Hollywood Reporter. Waititi, who recently helmed Marvel's Thor: Ragnarok, will also be starring as Adolph Hitler who is the boy's imaginary friend.
