(Kurosawa had previously turned to Shakespeare for inspiration in Throne of Blood, his 1957 adaptation of Macbeth).
With 1957's Throne Of Blood, his seminal Macbeth adaptation, Kurosawa proved himself capable of transposing Shakespeare to feudal Japan while seamlessly incorporating Noh and Kabuki traditions.
Kurosawa resists the description of ''Ran'' as his ''version'' of ''King Lear,'' in the manner of his free, 1957 adaptation of ''Macbeth,'' titled ''Throne of Blood.''
As I remember it, the weird fashion for Shakespeare adaptations in the '90s (everything from various Hamlets to fascist-styled Richard III) only gave weathered cinephiles reason to fondly remember both Ran and Kurosawa's Throne of Blood (1957), which trumped all other Bard films by jettisoning the Elizabethan texts without ado and focusing instead on the fablelike stories.
Unlike Kurosawa’s Throne Of Blood (1957), which sticks fairly close to Macbeth, Ran only vaguely resembles its Shakespearean source; the director claimed he was well into the planning stage before realizing the similarity, at which point he deliberately incorporated it.
Inspired by Shakespeare's "King Lear" in the same way Kurosawa's "Throne of Blood" was influenced by "Macbeth," "Ran" was the rare foreign language film to not only get multiple Oscar nominations, including best director, but to actually take home a statuette (for costume design).
