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.
