Directed by Akira Kurosawa with himself and William Shakespeare (and others) credited in the writing credits of this DVD of the 1957 film "Throne of Blood", it shows the integrity of the man willing to acknowledge Shakespeare as an original source, an approach not always adopted by modern writers and filmmakers. However, it also poses a problem for western audiences almost complelling them to look for "the Shakespeare" in this deeply Japanese film. This approach is unfortunate, to say the least, because it often immures them from the Japanese culture, occasionally even seeing it as a hindrance to seeing the Shakespeare, leaving them disappointed.
Kurosawa (1910-1998) was undoubtedly one of the greatest filmmakers of all times, directing thirty films in his fifty-seven year career, all of which have his trademark direction, i.e. multiple cameras, long lenses, deep focus, unusual angles, fast-editing and the film's graininess. He also edited his own films and saw this as the really creative aspect.
This "Macbeth" inspired, intensely Japanese film is one of Kurosawa's best but it is best to view it as that, a deep insight into Japanese culture rather than a Shakespearean re-make. The DVD has a few bonus features.
