Throne of Blood

Throne of Blood , Kumonosuj? , literally, Spider Web Castle is a 1957 Japanese film directed by Akira Kurosawa. The film transposes the plot of William Shakespeares play Macbeth to feudal Japan, with stylistic elements drawn from Noh drama.

When the two return to Tsuzukis estate, he rewards them with exactly what the spirit had predicted. As Washizu discusses this with Asaji, his wife, she manipulates him into making the second part of the prophecy come true by killing Tsuzuki when he visits. Washizu kills him with the help of his wife, who gives drugged sake to the lords guards, causing them to fall asleep. When Washizu returns in shock at his deed, Asaji grabs the bloody spear and puts it in the hands of one of the three unconscious guards. She then yells murder through the courtyard, and Washizu slays the guard before he has a chance to plead his innocence.Tsuzukis vengeful son Kunimaru and an advisor to Tsuzuki and rival of Washizu named Noriyasu both suspect Washizu as the murderous traitor and try to warn Miki, who refuses to believe what they are saying about his friend. Washizu, though, is unsure of Mikis loyalty, but he wants to trust his friend and he still plans to let Mikis son be his heir, since he and Asaji have been unable to bear a child of their own. ........
