Before Him All Rome Trembled

Before Him All Rome Trembled (Italian: Avanti a lui tremava tutta Roma) is a 1946 Italian musical war melodrama film directed by Carmine Gallone and starring Anna Magnani, Tito Gobbi and Hans Hinrich. Ada and Marco are a pair of opera singers, who moonlight working for the Italian resistance at the time of the German occupation of Rome during the Second World War. They are sheltering a British soldier with whom they make contact with the advancing Allied forces. Sylistically the film is a hybrid between filmed performances of opera, and a neorealistic resistance melodrama.
The title refers to Giacomo Puccini's "Tosca", which is performed during the film.
