I just remembered another film I've seen with Tatsuya Nakadai.
Akira Kurosawas Yojimbo with Toshiro Mifune.
Nakadai seemed to replace Mifune in Kurosawas later films didn't he?
I don't think I've seen a poor Kurosawa film yet, and I've seen quite a few now.
(Actually I'm watching Red Beard (Akahige) tonight, so I'll let you know...)
Mifune and Nakadai in Yojimbo...
