I'm still digging for more info, but the Japanese movie, AKANBO SHOUJO, has finished shooting and is slated for a 2008 release. Why should you care? Because it's based on a horror manga by Umezu Kazuo whose DRIFTING CLASSROOM is one of the only manga I can bring myself to read because it's one of the only manga in which this happens to bratty elementary schoolchildren:

AKANBO SHOUJO is about a traumatized young woman, Yoko, returning to her decrepit family mansion where a jealous deformed baby sporting an adult brain is hidden in the attic. The company-provided synopsis blithely notes, "Also, her mother, Yuko, has lost her mind."

The director of this flick is none other than Yudai Yamaguchi who directed BATTLEFIELD BASEBALL, MEATBALL MACHINE and CROMARTIE HIGH SCHOOL. So the director of CROMARTIE HIGH SCHOOL + a deformed and crazy baby + the writer of DRIFTING CLASSROOM = Tomorrow's Classic Movie...Today!
