The film in fact did not impress Mussolini, but still premiered at the Venice Film Festival and was quite successful. In 1943 he made "Harlem", set in the US and critical about the American lifestyle, with afro-American and colonial British war prisoners employed in extra roles as colored characters. Gallone also had a passion for making films that were linked to, or inspired by, the world of opera. These include "Casta Diva" (1935), "Il sogno di Butterfly" (Butterfly's Dream) (1939 and the remake of 1954) and "Puccini" (1953). After the revival of Italian film Gallone went back to work at home permanently in 1940. He directed not only more historical films like "Messalina" (1951) and "Cartagine in fiamme" (1960), but also some comic films in the "Don Camillo" series starring Fernandel and Gino Cervi. The comedy "Carmen di Trastevere", made in 1963, was the last film of his long career. Having directed more than one hundred films, Gallone is noted as one of the most prolific filmmakers in the history of Italian cinema, active both in the silent and sound eras.
