I recently watched this movie in a long flight and even with the not so perfect environment I viewed this in I have to say this movie was great. So much so that I skipped any sleep and watched part 2 and 3 immediately afterwards in one sitting (a wise decision since those were great too, specially Overheard 2 which was my favorite of the three)
The movie revolves around 3 police officers who work in the surveillance department and are trying to nab a financial firm suspected of being involved in criminal activities and insider trading. The plot while not really unique is executed well. The main focus of the story however is the trio of Lau Ching-Wan (who plays the head of the 3) Louis Koo and Daniel Wu whose character development and the interaction among them makes the story interesting at all times. Their acting was great and realistic and the movie direction really brings out their best. Another screen presence that really makes an impact is Michael Wong who plays the part of a corrupt financial mogul really well. The combination of witty and brutal in his performance and dialogues are very well crafted and add a lot of depth to the movie
Without spoiling too much I would really recommend you try out this movie if you like the crime/thriller genre and like movies with more to it than all the mediocre stuff that Hollywood has been mass producing for a while. Hong Kong really knows how to make great movies and this one's no exception
