Kurosawa employed a number of recurring themes in his films: the master-disciple relationship between a usually older mentor and one or more novices, which often involves spiritual as well as technical mastery and self-mastery; the heroic champion, the exceptional individual who emerges from the mass of people to produce something or right some wrong; the depiction of extremes of weather as both dramatic devices and symbols of human passion; and the recurrence of cycles of savage violence within history. According to Stephen Prince, the last theme, which he calls, "the countertradition to the committed, heroic mode of Kurosawa's cinema," began with "Throne of Blood" (1957), and recurred in the films of the 1980s.
