Looks like Wong Kar Wai is still Wong Kar Wai. Too bad we don't have Doyle to storm off the set in a fit of rage this time.

In real life, do you know who practiced Bruce Lee in doing martial arts?

Technically speaking, Yip Man was Bruce Lee's Wing Chun teacher.
However, the elder/senior students passed on what they learned to the younger/junior ones, in this case it was Wong Shun Leung who directly mentored Bruce.

Wong Kar-wai's "The Grand Master" is said to have completed filming and is now entered the editing phase. Ultimately, Brigitte Lin did not make a comeback appearance. Zhang Ziyi's role is said to be that of a female killer/assassin. Zhao Benshan and Song Hye-kyo also appear.
The film began shooting in Guangdong last November and has been shrouded in secrecy. A Lunar New Year opening is still anticipated despite some delays.
It will compete against four powerhouse films: Chen Kaige's Zhao's Orphan, Zhang Yimou's Love Under the Hawthorne Tree, Jiang Wen's Let the Bullets Fly and Feng Xiaogang's You Are the One 2.

Already done? But it hasn't stretched on for two years yet!

Hard to believe, right ? hehe

I have doubts that they've actually finished filming as Tony said they would be filming in South China (so far they've been mostly filming in North China).

Actress Anita Yuen Wing-yi spoke about her husband Julian Cheung Chi-lam's involvement in "The Grand Master".
She said that he has become much thinner because he was busy with Wong Kar-wai's new film.
She said, "I don't know what Wong Kar-wai told him. Now whatever he eats he has to weigh first and always work out until very late. His weight loss process seems to reach obsession level. He shrinks down day by day and I swell up day by day. I don't even know what role he is playing. When I called the film company to ask, they said it was none of my business."

Martial arts actor Bruce Leung Siu-lung aka Bruce Liang (Gallants, Kung Fu Hustle) confirmed in an interview that he would be starring in The Grand Master.

CSB: You’ve done a lot of comedies since your comeback. Do you want to tackle some more dramatic roles?
Bruce Leung: Since Kung Fu Hustle, I’ve actually done 12 or 13 films in all different genres, not just comedies. I’m actually going to go to Shanghai to shoot a film with Chow Yun-Fat that does not require me to do any martial arts. And there is another one with Tony Leung Chiu-Wai. I will also be in Wong Kar-Wai’s movie about Ip Man, playing one of the masters.
