The official website for Shion Sono's Exte - Hair Extensions (Ekusute) is online, although at present it's just a home page.
The screenplay for Exte - Hair Extensions was written by Sono. The movie stars (listed order corresponds to order on official website) Chiaki Kuriyama, Ren Ôsugi, Megumi Satô, Tsugumi, Eri Machimoto, Miku Satô, and Mirai Yamamoto.
Toei Company Ltd. (Tôei K.K.) plans to release Exte - Hair Extensions theatrically in Japan in February of next year.

Sono's been damn busy lately..still waiting for NDT after being kinda half and half with Strange Circus - I think he has better stuff in him yet.
I expect this to be a satire about J-horror clichees, ushering in the much overdue death of that beyond annoying subgenre. I mean it's about cursed hair extensions. Awesome. Just awesome. Sono kicks ass and I cannot wait to catch up to the dozen or so films he's made in the past year or so.
This film was also screened at the American Film Market recently. A short review of it I found on the Dread Central (http://www.dreadcentral.com) website doesn't make it sound so promising anymore:
"The Japanese obsession with hair finds its way to the forefront – and the workplace of sexy star Chiaki Kuriyama. The actress plays Yuko, a hair dresser whose life is turned into chaos when the cursed hair of a murder victim finds its way into her shop of hair extensions.
Eclectic director Sion Sono (Suicide Club) is one of the best new talents in the genre, but Exte - his first big studio film with Toei - is a total wash-out. After sitting through six Ju-On films and countless other J-horror knock-offs, the notion of killer hair only feels redundant. The story is too thin to sustain a feature and Sono’s attempt at quirkiness backfires into annoyance and boredom. A wasted effort from an otherwise talented filmmaker."
So it's being played straight? Crap.
