After the enormous international success of "Rome, Open City", Rossellini was able to obtain funding from international investors, particularly in the U.S. He decided to make a film about the liberation of Italy from the Allied invasion in 1943 to the end of World War II in 1945. Unusually for a film with much dialogue not in English, Metro-Goldwyn-Mayer took over distribution of the movie in the United States (from smaller firm Burstyn &amp; Mayer), helping its visibility.
