For the Italian release all the actors were dubbed into Italian.Even though you can often see their lips speak English, the Italian sounds that come out of them are for the most part quite beautiful.(After all, Brass had 18 years to contemplate these ideas and continually rewrite the script.) The result is a film that goes beyond being profoundly heart-rending.
So instead of Frank Finlay’s voice, we hear Paolo Bonacelli’s voice, which is excellent, but I still prefer Frank’s speaking voice. The name he gave to Frank Finlay’s character is John, which is equivalent to Giovanni.
By the way, the language choices in this movie can be a bit confusing.
