Musashi Myamoto Trilogy

[Matthew H. Bernstein]

Hi,

I'm preparing to teach the Inagaki Samurai Triology for the first time and 
am finding only the chapter in Alain Silver's SAMURAI FILM and the chapter 
in ARCHETYPES IN JAPANESE CINEMA.

Is there no other scholarly work on the trilogy in English? (I'm recalling 
that David Desser discusses it briefly in SAMURAI FILMS OF AKIRA KUROSAWA).

I'm also curious about any analyses of the 1963 CHUSHINGURA.

Thanks for any leads.

Matthew
