http://zepy.momotato.com/2008/10/14/kaiji-live-action-movie-in-the-works/ The link says it all. And who they casted as Kaiji... wat.
Watarase Film Commission has put up a
notice on their site announcing that they are recruiting 70 extras for a Kaiji live action movie to appear in the restricted rock paper scissors game on the Espoir. The director for the movie is Gokusen director Satou Touya.
Fujiwara Tatsuya who starred as Light Yagami in the Death Note movie will be playing the role of Kaiji (what!?).
