Watch VoirFilms. Although released anonymously, as was the custom with all films produced by the Italian Navy, La Nave Bianca is the first feature-length effort directed by Roberto Rossellini; it is also very much the work of its co-writer and supervisor Francesco De Robertis. The film combines a documentary look at the Italian Navy during World War II with newsreel combat footage and a scripted love story performed by non-professional actors.
