Comparative explanation of the soundtracks of  Yôjinbô (61), by Akira Kurosawa with music by Masaru Satô, and Per un pugno di dollari (64), by Sergio Leone with music by Ennio Morricone. Leone's film is an unacknowledged remake of Kurosawa's. Was Morricone inspired by Satô? Do they have anything in common?
