kurosawaesque ronin and wandering cowboy gunslingers are the same kind of guy and honestly i think all english dub ronins should talk a little like cowboys
I love that this is just textual for film in the 20th century, like two of the most iconic westerns ever were adaptations of Kurosawa films: Magnificent Seven is a remake of Seven Samurai, and Fistful of Dollars is a remake of Yojimbo!.
Yet Kurosawa himself was clearly influenced by western culture and movies (he adapted a number of shakespeare plays, including his film Kumonso-Jo, his version of MacBeth and one of my favorite movies ever) to the point that a lot of his contemporaries and critics accused him of pandering to Western audiences, who clearly ate up his stuff by the handful.
In turn, too, a lot of the westerns that took inspiration from samurai films fed back into Japanese film and Anime, so that the two have been connected ever since.
