Keanu Reeves starring as Spike Spiegel in the upcoming live-action adaptation of Cowboy Bebop or not, it's not hard to see that he's a driving force behind the movie getting made at all. If THAT doesn't get you some Japanophile geek cred, what does?
Well, I guess starring in 47 Ronin might help. The film is an upcoming live-action movie based on a famous Japanese tale of 18th-century samurai-- 47 of 'em, as you may have guessed --who hit the road to try and take down the guy who killed their master, leaving them "ronin" (a ronin is a samurai without a master, although it's also used these days colloquially to refer to a high school graduate who failed their college entrance exams and is studying to retake them).
The original story has been remade dozens of times in Japan, perhaps not entirely unlike the Arthurian legends in the west. In addition, one of the most popular themes of the ukiyo-e woodblock prints that are said to be a precursor to manga was the tale of the Forty-Seven Ronins.
Wanted and Fast & Furious screenwriter Chris Morgan wrote the script for the film, and it's going to be directed by Carl Rinsch, who may have dropped out of the Alien prequel to direct this film. It will be produced by Scott Stuber and Pamela Abdy.
