47 Ronin is the addition of four Japanese actors into the film. Since the story is a Samurai-based Asian-inspired epic, it is only right that more Asian actors are slated for it. The four actors to act side-by-side Keanu Reeves are Tadanobu Asano, Kou Shibasaki, Rinko Kikuchi, and Hiroyuki Sanada.Hiroyuki Sanada played Dogen in the final season of "Lost". The production crew of 47 Ronin is currently busy building sets and making everything else ready for the first shoot. Keanu Reeves' last movie was Henry's Crime, which is still being shown worldwide.
