The only real CBM news I see anime wise, is Dragon Ball and Bleach. And while they are good animes, there are many more less generic anime's that deserve movies.
Sailor Moon
Story: The series focuses on the Sailor Senshi, a group of magical girls tasked with defending the earth.
This wouldn't by any means be an easy adaption. It might be a rare case where a "dark and gritty" adaption might be the better route (ala Sucker Punch).
As for director: Wachowskis
Spice & Wolf
Story: The series focuses on Holo, a wolf deity of wheat, who travels with a merchant named Kraft Lawrence.
While the series is heavily fantastical, there needs to be a lot of focus on the merchant and trade elements.
As for director: Peter Jackson or Guillermo Del Toro
Welcome to the NHK
Story: The series focuses on a twenty-two-year-old antisocial individual who gets aid from a strange girl who seems to know a lot about him, despite never meeting him before.
A personal favorite of mine. The series revolves around conspiracies. There would need to be a strong psychological element, while still having a comedic undertone.
As for director: David Fincher
Trigun
Story: The series focuses on an outlaw called Vash the Stampede, who has a ten million double dollar bounty on his head.
There would need to be a lot of slow-mo action.
As for director: Quentin Tarantino
FLCL
Story: The series focuses on a boy whose boring life is changed by a girl on a motorbike.
The series is heavy on spontaneity and psychedelia, while keeping a dark undertone. All three would be needed for a successful film adaption.
As for director: David Fincher
