A samurai film must include samurai warriors, sword fighting, and historical setting. Samurai warriors, in film, are differentiated from other warriors by the code of honor followed to honor the samurai's leader. A samurai must perforce be skilled in warfare and martial arts and ready to defend his honor even to his death. If not able to defend his honor, a samurai may choose to commit self-disembowelment, seppuku, in order to save reputation or "face". Instead, a samurai may exact vengeance in a case of the loss of someone the samurai cared about, such as occurs in the film "Harakiri". In "Harakiri", Hanshiro Tsugumo takes revenge on the house of Kageyu Saito for the loss of his adopted son-in-law, who was forced to commit suicide by the house of Kageyu Saito. The house of Kageyu Saito refused to give the son-in-law money. Because he had asked to commit suicide he was forced to perform self-disembowelment, with a remarkable twist not revealed in this discussion. Hanshiro knows an example was unrightfully made of his son-in-law in order to discourage the asking by impoverished samurai for donations from the house of Kageyu. In film, motivation may vary but the samurai's behavior is to maintain honor even in death and is perpetuated by the code of bushido.
