After the first two instalments of this trilogy I wondered if we'd be getting another prequel or a sequel to the first film; as it turns out this film is both! We follow Chan Wing-yan in his undercover role working for Sam in the run up to a major deal and we also observe Inspector Lau as he works to make sure nobody can connect him with Sam, his erstwhile employer, so he can become an honest police officer. The problem for him is that his boss Yeung is also searching for any of Sam's moles left in the force. Doctor Lee takes a much greater role in this film as Chan Wing-yan is ordered to see her after assaulting a Triad member in a restaurant and Lau sees her to learn more about Chan Wing-yan's activities.While I think this was probably the weakest of the three films it was still pretty good and anybody who enjoyed the first two films really should watch this as it neatly wraps up the story. Having missed the second film Tony Leung and Andy Lau are back as Chan Wing-yan and Lau and once again they put in fine performances; other notable stars are Leon Lai as Yeung and Kelly Chen as Doctor Lee the psychiatrist. The earlier parts of the film are mostly action free but there are some good action scenes later on, there are also some nicely humorous scenes as Chan Wing-yan tries to avoid being hypnotised by Doctor Lee.

While this is a great film with an incomparable score and outstanding cinematography, it leaves a lot to be desired.It is really not necessary as the first two films really give us all we need. It is light on action and heavy on psychological trauma. Andy Lau as Inspector Lau has taken care of all the moles - or he thinks he has. he is not sure and wants to be clear there is nothing tying him to Sam so he can be the good cop he wants to be. SP Leung is a creepy fellow and we are never sure just what he is. Is he a mole, or just a crooked cop. It is never clear.I was glad that Kelly Chen got a much bigger role as Dr. lee, but it would have been even better if we saw a relationship with Yan. It was obvious that she had love for him, but it never blossomed on screen. Yes, I know that would be a violation of the doctor-patient relationship, but it was there under the surface. Why didn't it come out.We got to see quite a bit of Tony Leung in this film, and that is always a good thing.It was very distracting the way the film jumped back and forth through time. It was trying to tie up the loose ends, but it was disconcerting.It could have been an outstanding film, but it'll just have to be great to see the actors and enjoy their performance.

What exactly is her intention when dealing with Ming? Nick_Vorobyov said that she was contacted by Shen and was trying to test if Ming is a spy.But that doesn't make a lot of sense.Especially when she received the tape from Yan. and she called Ming without even listening to it.If she does not trust Ming, why doesn't she at least see what the tape is about?Also, she seemed more or less shocked when Ming confessed to her "I don't want to be Sam's guy anymore."So when she showed Yan's profile to Ming(or did she do it unintentionally?) on her computer and later hinted him the password, what exactly was she trying to do?

This time around, we have the returning Tony Leung, Andy Lau, and the new comer Leon Lai to light up the screen for Infernal Affairs III. The three are arguably the biggest pop stars in Hong Kong since the 80's. Does it make the movie any better, I don't think so. These superstars just act like superstar actors (essentially playing their cool selves on screen) and I don't think they are great in this one. They have better performances in other movies. The cool monotone blackish production design doesn't necessarily make the movie cool and modern, not even the computer, gadgets, GPS..., in fact it comes across as rather pretentious and boring. How does it compare to the original Infernal Affairs? I like the first one better, at least it has some good story telling there, not necessarily original: undercover cop, mole, I don't think it's all that original, but you don't necessarily to be original to be good. This sequel rehash the basic premise of the first one, do some more plot twisting and psychological drama there, which I somehow find totally unnecessary other than let's make another sequel to cash in from the first one. It's not a good sequel and definitely not a very good movie either.
