O sole mio

My Sun is a 1946 Italian war drama film directed by Giacomo Gentilomo. It is considered one of the earliest films belonging to the genre of Italian neorealism, due to its use of exterior scenes and the inclusion of non-professional actors. It was shot at the Scalera Studios in Rome and on location around Naples. The film's sets were designed by the art director Alberto Boccianti. The film is set during the Four days of Naples in September 1943. Its title refers to the Neapolitan song "’O sole mio".
