You do not have to be a samurai film buff to enjoy the intricacies of feudal Japan portrayed in Akira Kurosawa's Throne of Blood.
You do not have to be a Shakespeare nut to appreciate that Toshiro Mifune's portrayal of a lord driven to madness by ambition and paranoia is, in fact, the story of MacBeth.
However, if - like me - you are both, you are really going to love this film.
The three witches become one evil spirit, and Birnam Wood becomes the eerie Spider's Web Forest. Though not using the actual dialogue of the script, and moved to feudal Japan, Throne of Blood is celebrated as one of the best film adaptations of the Bard.
