I think the most impressive long take with complex staging that I saw, in recent memory, was the opening shot in Hou Hsiao-hsien's Flowers of Shanghai
, with all the men sitting at the table playing drinking games and the flower girls behind them. Did you know that one of those girls is a Category III actress in Hong Kong, though I can't remember which one?
BTW, I tried to email yun-fat to encourage him to sign up, but my email has been rejected by the mail distributor. Has anyone been in contact with him lately, other than on the NYT site?
