Youtube user forbesnation has put together a two-part documentary discussing “the Western influences and influence of legendary director Akira Kurosawa”. The work, which was made as a High School project, perhaps feels a bit patchy, but has nevertheless been edited together quite nicely. You will probably recognize the sources used for the video and much of the audio material.
For some reason, currently only Part 2 of the documentary is available.
Update: Part 1 is now available, and can be viewed here.
