The Hong Kong director has embarked on a 3-month filming process, testing the 3-D equipment and techniques he will later use for making "New Dragon Gate Inn", the Beijing News reports.

Tsui is hoping to release the test film as a standalone feature, the report says.

Actress Charlie Young has been invited to star in the test film which is about the lives of urban women.

Young told the newspaper, "Filming in 3-D is quite interesting. Every time I finish a scene, the first thing I want to do is stride behind the camera and check out the effect with 3-D glasses."

Tsui's 3-D crew received training from Chuck Comisky, visual-effects supervisor of James Cameron's "Avatar".

"New Dragon Gate Inn" is a remake of the 1992 classic film "Dragon Inn", which follows Ming Dynasty General Chow Wai-On who fights the power-hungry eunuch Tsao Siu-Yan at a deserted inn called Dragon Gate. Tsui produced that film.

The cast is yet to be announced for the remake.

Filming will officially begin in October.
