kobudō and traditional budō indicate that the samurai were as practical on the battlefield as were any other warriors. Despite the rampant romanticism of the 20th century, samurai could be disloyal and treacherous (e.g., Akechi Mitsuhide), cowardly, brave, or overly loyal (e.g., Kusunoki Masashige). Samurai were usually loyal to their immediate superiors, who in turn allied themselves with higher lords. These loyalties to the higher lords often shifted; for example, the high lords allied under Toyotomi Hideyoshi were served by loyal samurai, but the feudal lords under them could shift their support to Tokugawa, taking their samurai with them. There were, however, also notable instances where samurai would be disloyal to their lord (daimyō), when loyalty to the emperor was seen to have supremacy. In popular culture Samurai figures have been the subject for legends, folk tales, dramatic stories (i.e. gunki monogatari), theatre productions in kabuki and noh, in literature, movies, animated and anime films, television shows, manga, video games, and in various musical pieces in genre that range from enka to J-Pop songs. Jidaigeki (literally historical drama) has always been a staple program on Japanese movies and television. The programs typically feature a samurai. Samurai films and westerns share a number of similarities, and the two have influenced each other over the years. One of Japan's most renowned directors, Akira Kurosawa, greatly influenced western film-making. George Lucas' Star Wars series incorporated many stylistic traits pioneered by Kurosawa, and Star Wars: A New Hope takes the core story of a rescued princess being transported to a secret base from Kurosawa's The Hidden Fortress. Kurosawa was inspired by the works of director John Ford, and in turn Kurosawa's works have been remade into westerns such as Seven Samurai into The Magnificent Seven and Yojimbo into A Fistful of Dollars. There is also a 26 episode anime adaptation (Samurai 7) of Seven Samurai. Along with film, literature containing samurai influences are seen as well. As well as influence from American Westerns, Kurosawa also adapted two of Shakespeare's plays as sources for samurai movies: Throne of Blood was based on Macbeth, and Ran was based on King Lear. Most common are historical works where the protagonist is either a samurai or former samurai (or another rank or position) who possesses considerable martial skill. Eiji Yoshikawa is one of the most famous Japanese historical novelists. His retellings of popular works, including Taiko, Musashi and
