Claim	C010

Claim as Received¶

Kurosawa's Throne of Blood (1957) is based on Macbeth, The Bad Sleep Well (1960) is based on Hamlet, and Ran (1985) is based on King Lear.

Claim as Clarified¶

Kurosawa's Throne of Blood (1957) is based on Macbeth, The Bad Sleep Well (1960) is based on Hamlet, and Ran (1985) is based on King Lear.

BLUF¶

Throne of Blood (1957/Macbeth) and Ran (1985/King Lear) are universally recognized Shakespeare adaptations. The Bad Sleep Well (1960) draws on Hamlet but scholars describe it as a loose adaptation — Kurosawa maintained a 'loose grip' on Shakespeare, using Hamlet as 'an echo chamber and fun-house mirror rather than a detailed contour map.' The claim is substantially correct but overstates the directness of The Bad Sleep Well's relationship to Hamlet.
