Steel (Italian: Acciaio) is a 1933 Italian drama film directed by Walter Ruttmann and starring Piero Pastore, Isa Pola and Vittorio Bellaccini. The film was shot on location at the steel mills in Terni in Umbria. It was based on the novel Giuoca, Pietro! by Luigi Pirandello. With its semi-documentary style it was one of a number of films made in the Fascist era that serve as a precursor to Italian neorealism which emerged in the mid-1940s.
