The characters watch "The Seven Year Itch" in its original language (English) without captions translating the lines neither dubbed, which is highly unlikely for a cinema audience in a non-speaking language. Movies were (and are) either dubbed in the country's language or subtitles are included.
In the 1965 segment, when Xico and Olga are discussing in front of the theatre, a poster from the film "Dio, come ti amo!" is visible, a film that was released in 1966.
