I know many people came to see this movie because of the two big stars, Tony Leung and Aaron Kwok, and that's completely understandable. Both male leads still have their charisma and have portrayed the detective's hardships and glory very convincingly. However, I highly recommend everyone to pay close attention to the performance of the female lead, played by Du Juan. She truly shines and takes the audience back to the old Hong Kong era. In the past, men needed women to take care of all aspects of their lives in order to look good in public, even if it meant eliminating adversaries. Du Juan's charm and tactics are portrayed excellently, giving a performance that rivals her previous collaboration with Tony Leung's Tang Wei. Aside from the familiar story, the acting prowess of these big stars is something I highly recommend to everyone.
