Justin Lin is a busy guy. He's already directed three films in the Fast and the Furious franchise and looks to be at the helm for this adaptation.
I have never heard of the manga but it contains samurais so you can expect some great samurai swordfighting action.
Manga adaptations haven't been very good as of yet in Hollywood with Katsuhiro Otomo's 'Akira' being stuck in development hell and one that was actually made was Akira Toriyama's 'Dragonball'. 'Dragonball: Evolution' anyone???
Let's hope that this film will be faithful to the manga.
