Fan Casting Katsushirō in Seven Samurai

Katsushirō is a young man born into the samurai class. He has left home to make his own way, and when he sees Kambei cut his top knot, an important status symbol of samurai, in order to save a child from a bandit, he insists on being his apprentice. Though he lacks skill or experience, he is deeply compassionate, cares about the plight of the farmers, and shares a similar sense of morality as Kambei.
