Chan Wing Yan:Should I salute you?
Lau Kin Ming:No, don't. How long have you been an undercover?
Chan Wing Yan:I've followed Sam for 3 years; I had several other bosses before. All together, it's been 10 years
Lau Kin Ming:10 years? I should salute you, instead.
Chan Wing Yan:I just want an identity. I want to be a normal man.
Lau Kin Ming:Getting tired?
Chan Wing Yan:You've never been a mole. You won't understand. Too bad I still can't find the stooge. I'll take him down if I've found him.
Lau Kin Ming:Don't worry. Let me give you back your identity, I'll open your file, but I don't have the password.

more than just entertaining, 9 March 2005
Author: magsy from Canada

This movie is well-made, stylish and extremely entertaining. However, as stated by the review from a Hong Kong viewer, there is also depth and subtlety rarely found in action/thrillers. It is this depth that makes this movie brilliant. The depth of this movie is best served by the understated yet deeply moving performances of the main characters. Viewers are allowed into the inner changes of these characters and before long, the viewers begin to care about them, be it the "good guy" (Yan) or the "bad guy" (Ming). The rest of cast successfully relate the complicated and exciting plot to the viewers, and all the supporting performances are almost flawless, perhaps with the exception of the female psychologist who seems sadly one-dimensional. I grew up in Hong Kong but has since lived most of my life in Canada. With this duo-cultural background, I have mixed feelings about the Hollywood remaking of this movie. On the one hand, I am happy for the Hollywood recognition of this great movie by remaking it. On the other hand, I would hate to see how badly sabotaged the end result would be. Some things just do not translate. As a minimum, I hope the great director Scorcese will make good use of the major plot line and generate a haute thriller and with the excellent cast, develop some in-depth characterization. The Chinese philosophy and the spirit of the original film is better left undisturbed.
