This is perhaps my favorite Shakespeare adaptation film. Kurosawa controls what the camera sees through light, smoke, and movement in a masterful way. Character entrances/exits and scene transitions take on a seamless and ghostly quality. The scenes in Spider's Web forest are particularly interesting.

The best part is, despite the big cultural gap, this is in fact a VERY faithful adaptation of Macbeth. If you've not seen it, don't expect swash-buckling adventure like Sanjuro or Seven Samurai.
