WKW's next film: The Eternal Snow Beauty starring Brigitte Lin?

In 2009, Hong Kong newspapers and magazines reported on Brigitte Lin's return to film.
Originally thought to be a part as Yip man's wife in "The Grand Master" it was later speculated that she would star in a different film:

"Brigitte Lin has reportedly decided her return will be with Wong Kar-Wai in an adaption of "The Eternal Yin Hsueh-yen" (aka The Eternal Snow Beauty).
She turned down the role of Ip Man's wife in "The Grand Master", as the part wasn't tailor-made for her, to play the lead in this film.
Filming won't begin until after "The Grand Master" is completed, Tony Leung wishes to participate.
Taiwanese writer Pai Hsien-yung previously said: "Brigitte Lin is my old friend. She has always wanted to act in movies or dramas adapted from my stories such as "The Eternal Yin Hsueh-yen", "A Touch of Green'" and etc. I've extended my invitations in the past, but she was unable to take up the offer and it was much regretted."
