With the movie out sometime next summer, a special The Making Of was aired recently, giving audience a behind the scenes look on the project. Since I don't get half of what they're saying, I'll just post caps instead ^^;
My only complains thus far is that the actors look nothing like their anime counterparts, which is a given of course, but at least the live action porno version dressed them up accordingly lawl. Also, Takano's a wee bit too old, while Oishi reminds me of Hugh Laurie for some reason, which isn't that bad a thing, although considering he's supposed to be on the brink of retirement. Well, at least both actresses playing Satoko and Rika are cute =D Eiko Shimamiya who has done the anime OP themes will be doing one for the movie as well. More info at the main site, or you could get yourself the making of special here.
