” ..1941 Japanese [film] ‘The 47 Ronin’...”
I’ve seen it. Most of the action (i.e. fights) take place off-screen, with the on-screen characters learning about them via letters and messages.
It is not Kurasawa.
On was the other hand, the Keanu Reeves (2013) version is just silly. Witches, and dragons, and demons, oh my! And Reeves as a half-breed samurai? Nothing to do with the Classic Japanese epic at all.
One of the best versions of the story with Morgan Freeman (!?!) as the unfortunate rural daimo Ako, But the setting was changed to some vague, medieval, eastern European/Byzantine Empire (to justify the decidedly diverse international cast?). It was still closer to the original than the 2013 movie.
