Paradise Kiss Vol 1
Set in the world of fashion, "Paradise Kiss" is based on a hit cartoon series by top female manga artist Ai Yazawa that is now in its fifth series and has sold more than 6 million copies. The series, published in Japan by Shodensha, has been translated into 10 languages and proved a hit through much of Asia. It is available in English through Tokyopop.
But before you get all excited about seeing the film on the big-screen, Fox isn't currently planning on adapting it as a Hollywood remake. No, it'll be a Japanese-language film, with a reportedly $3-4 million budget and involving the company IMJ Entertainment, which is also working on this year's adaptation of Osamu Tezuka's MW and which also worked with Yazawa before, on the Nana films.
On the other hand-- VIZ Pictures put out the Nana film in North America a while back, and by the time this movie is out, they'll have access to a handy-dandy movie theater in San Francisco. So there may yet be hope for fans to get a chance to see it. But it still won't be a Hollywood flick.
...If it WAS a Hollywood movie, though...how would you cast it?
Hollywood's in trouble, and they're looking to work with stuff that has built-in fanbases. Even though Fruits Basket has been a top-selling manga for a long time, Naruto has a larger overall audience. So do Bleach and Death Note. Sad, but true.
