It's often stated that Claudia Cardinale's real voice is first heard in Fellini's 8 1/2. However, that is for Italian films which are dubbed after filming since CC didn't speak much Italian and Italian directors thought her voice wouldn't appeal. Actually, Upstairs and Downstairs was the first film to use her voice (in English) in a minor role. Les Lions sont lâchés is her first starring French role and is the first film that uses her real, distinctive voice. In fact, as the main star, she narrates a good portion of the film in French, her first language.
