Taika Waititi, Scarlett Johansson on "Jojo Rabbit"
New Zealand writer-director Taika Waititi's rollicking World War II satire centers on a German boy, an aspiring young Nazi, who fantasizes about his best buddy Adolf Hitler while discovering his mother is harboring a Jewish girl in their house. Audacious and touching, the film has been nominated for six Academy Awards, including Best Picture. Tracy Smith talks with Waititi and with Oscar-nominee Scarlett Johansson.
