Apropos of nothing, I just watched a movie called PAULINE'S LIFE, a dull slog through the last crazy weeks in the life of Pauline Chan, who killed herself in 2002. In trying to find more info on this film (of which there is little), I came across an ATV series called LEGEND: A DREAM OF DESIRE, in which Alice Chan, who we were discussing above, played a beauty pageant loser named Pauline who is signed into Category III films by her mother (I think this series aired before Pauline's death, but I'm sure it didn't help her mental state any!). Interestingly, in the sequel to this series, LEGEND 2, Alice Chan plays....Anita Mui. So if the Anita Mui biopic is indeed a big screen affair, it looks like they've chosen an actress with some history in the part.
