 During the filming of The Bread and Alley , his first film , Kiarostami disagreed with his experienced cinematographer about how to film the boy and the attacking dog . The cinematographer wanted separate shots of the boy approaching , a close up of his hand as he enters the house and closes the door , followed by a shot of the dog . Kiarostami believed that if the three scenes could be captured as a whole it would have a more profound impact , creating tension . That one shot took some forty days to complete . Kiarostami later commented that the breaking of scenes can disrupt the rhythm and content of the film 's structure , stating he prefers to let the scene flow as one .
