Returning to their lord's castle, samurai warriors Washizu and Miki are waylaid by a spirit who predicts their futures. When the first part of the spirit's prophecy comes true, Washizu's scheming wife, Asaji, presses him to speed up the rest of the spirit's prophecy by murdering his lord and usurping his place. Director Akira Kurosawa's resetting of William Shakespeare's "Macbeth" in feudal Japan is one of his most acclaimed films.
Throne of Blood is a 1957 Japanese epic jidaigeki film co-written, produced, edited, and directed by Akira Kurosawa, with special effects by Eiji Tsuburaya. The film transposes the plot of English dramatist William Shakespeare's play Macbeth (1606) from Medieval Scotland to feudal Japan, with stylistic elements drawn from Noh drama. The film stars Toshiro Mifune and Isuzu Yamada in the lead roles, modelled on the characters Macbeth and Lady Macbeth.
