Bicycle Thieves is the best-known work of Italian neorealism, the movement that formally began with Roberto Rossellini's Rome, Open City (1945) and aimed to give cinema a new degree of realism.[13] De Sica had just made Shoeshine (1946), but was unable to get financial backing from any major studio for the film, so he raised the money himself from friends. Wanting to portray the poverty and unemployment of post-war Italy,[14] he co-wrote a script with Cesare Zavattini and others using only the title and few plot devices of a little-known novel of the time by poet and artist Luigi Bartolini.[15] Following the precepts of neorealism, De Sica shot only on location (that is, no studio sets) and cast only untrained actors. (Lamberto Maggiorani, for example, was a factory worker.) That some actors' roles paralleled their lives off screen added realism to the film.[16] De Sica cast Maggiorani when he had brought his young son to an audition for the film. He later cast the 8-year-old Enzo Staiola when he noticed the young boy watching the film's production on a street while helping his father sell flowers. The film's final shot of Antonio and Bruno walking away from the camera into the distance is an homage to many of the films of Charlie Chaplin, who was De Sica's favourite filmmaker.[17]
