Keanu Reeves as a samurai?

It is being reported that Keanu Reeves may become a samurai in a new movie about the famous Japanese story of the 47 Ronin.  I don't know about this choice.  Keanu was ok as a "chosen one" in the Matrix movies but I don't see him as a samurai.  Couldn't they have found a more appropriate actor then he.  

What I liked about The Last Samurai or Letters from Iwo Jima was that the Japanese characters spoke Japanese.  I can't really get into historical movies about non-English speaking figures where all the characters in the movie speak English such as the new Tom Cruise movie Valkyrie where all the Germans speak English.  I assume that Keanu does not speak Japanese so the movie will be in English.

Can anybody think of some other actors that would be more appropriate for this movie?  Below is a brief description of the 47 Ronin story.  I am currently reading a book about the 5th Tokugawa Shogun Tsunayoshi.  It was during his reign that this event occurred and the book covers it so I will write more about the 47 Ronin later.

The revenge of the Forty-seven Ronin, also known as the Forty-seven Samurai,took place in Japan at the start of the eighteenth century. The tale has been described as the country's "national legend." It recounts the most famous case involving the samurai code of honor, bushidō.

The story tells of a group of samurai who were left leaderless (became ronin) after their daimyo (feudal lord) was forced to commit seppuku (ritual suicide) for assaulting a court official named Kira Yoshinaka, whose title was Kōzuke no Suke. The ronin avenged their master's honor after patiently waiting and planning for over a year to kill Kira. In turn, the ronin were themselves forced to commit seppuku — as they had known they would be — for committing the crime of murder. With little embellishment, this true story was popularized in Japanese culture as emblematic of the loyalty, sacrifice, persistence, and honor that all good people should persevere in their daily lives. The popularity of the almost mythical tale was only enhanced by rapid modernization during the Meiji era of Japanese history, when many people in Japan longed for a return to their cultural roots.
