This movie is all about the great beauty (Pauline) acted by Suki Kwan Sau Mei as triad leader's wife. Her beauty encouraged Daniel to become an undercover cop, however, he admires Pauline very much.With Anya as Daniel Wu's girl friend, not wonder he's searching for better alternative. Eric Tsang was great as the No. 1 leader in the triad but sill loyal and faithful to her charming wife - Pauline.

A surprisingly good 2001 Hong Kong film. There are several themes in this movie: good vs. evil, letting evil influence and take over one's mind, greed, power, poor vs. rich, conflicts with job duties, choosing money over friendship, etc. Daniel plays the character named Mike who is a good cop, turned undercover, turned bad guy/triad member. He is undercover as a triad and has been told by his boss that many undercovers have compltetly forgotten they are cops and taken the wrong path, he begins to wonder why he is a cop and lusts for the power that Brother Tin played by Eric Tsang has.Daniel Wu once again surprises with his hard to come by talent, his acting was once again superior to the others.The film has many messages and really makes you think, to me i did not expect the ending that happened as i did not expect with all the background that mike (wu's character) had that he would turn out to be what you see him to be. Cop on a mission is a good film and has twists that will keep you interested and it is worth every minute that daniel wu is in. Eric Tsang plays his part well but is more suited to comedy/action films in my opinion. However, this film is highly reccommended.

I found the DVD for sale, and the selling point for me was the casting of Eric Tsang as a triad gangster boss. Tsang was brilliant in 1998's 'Hitman,' alongside Jet Li, in my personal favorite of Li's films. Daniel Wu plays an undercover Hong Kong cop infiltrating the triads to build a case against Tsang's character. However, he soon finds the trappings of the gangster life impossible to resist. He will do anything to protect his identity and the lifestyle he enjoys as a high-ranking mob enforcer, which makes him equally dangerous to both sides of the law.Although you might find this movie in the Martial Arts section of your local video store, it really is not that sort of movie. Don't get me wrong, there is a fair amount of violence. But the gunplay doesn't resemble a ballet, and someone on the receiving end of a kick to the head is likely to be tied to a chair and helpless.

This is different then the usual undercover cop movie.The main character starts off as a normal HK cop working the beat until he decides to follow a suspicious character into a cafe, the guy who they are following freaks and a gun fight ensues resulting in a lot of bloodshed. The guy who they were following was a nobody in the eyes of the triads and gets away due to the fact that the main character is in shock to see what he has just done. He hates his salary as a patrol man and can't even afford to take his girlfriend out to dinner,he becomes involved with a triad boss and is given the choice to go undercover. Now this is where it is different instead of the viewer being forced to view the cliched bring the bad guys down and take them to justice, the viewer gets to see a man fly high and not want to come down. During the film we often bump in to the crook he chased into the cafe at the beginning of the movie he screws him over every time which effects him seriously at the end of the film( I won't spoil). There are many fresh situations that are new and creative for example when the main character first gets involved with the triads he is sent on a mission to rescue his in debt gambling addicted wife from crooks in Macau who will only let her go if he has sex with her and gives them a good show.The acting is excellent,good plot (especially the sub story between he head triad and his wife).I give the film ****/**** for originality that never ceased to amaze me, a great HK film.
