Question: 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 the samurai aspect in western film-making.[citation needed] George Lucas' Star Wars series incorporated many aspects from the Seven Samurai film. One example is that in the Japanese film, seven samurai warriors are hired by local farmers to protect their land from being overrun by bandits; In George Lucas' Star Wars: A New Hope, a similar situation arises. Kurosawa was inspired by the works of director John Ford and in turn Kurosawa's works have been remade into westerns such as The Seven Samurai into The Magnificent Seven and Yojimbo into A Fistful of Dollars. There is also a 26 episode anime adaptation (Samurai 7) of The Seven Samurai. Along with film, literature containing samurai influences are seen as well.
Is there an answer to this question: What western was inspired by 'Seven Samurai'?

Answer: The Magnificent Seven

Question: The classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC (some authors prefer to split this period into 'Classical', from the end of the Persian wars to the end of the Peloponnesian War, and 'Fourth Century', up to the death of Alexander). It is so named because it set the standards by which Greek civilization would be judged in later eras. The Classical period is also described as the "Golden Age" of Greek civilization, and its art, philosophy, architecture and literature would be instrumental in the formation and development of Western culture.
