Kurosawa's Ran vs. King Lear

Where can I find a book or a website that compares and contrasts Ran with King Lear? I just watched Ran with my mother and we were able to tie some of the movie characters to the play, but not all of them.

Any help would be appreciated.

has a good review of Ran, with plenty of reference to King Lear

the IMDB listing for Ran also has some good stuff. Just scroll down to the bottom where it says Check for other user comments.

The book on Kurasawa’s films is Donald Richie’s The Films of Akira Kurasawa, which does a pretty good job on the background of each film, and critiques it.
