Joe D’Amato’s first experience with erotic movies was in 1975. The movie was Emanuelle e Francoise le sorelline, with a wonderful Rosemarie Lindt, Patrizia Gori, Maria Rosaria Riuzzi and Annie Carol Edel (here named Karole Annie Edel). The name Emanuelle in this title was due to the big success obtained by the writer Emmanuelle Arsan, with an M less, to avoid copyright troubles.
