The plot of Cop on a Mission is hardly a new one. Cop goes undercover and gets seduced by the criminal lifestyle. It has been done a million times before but this still has something to offer.Daniel Wu plays Mike, a cop who is becoming increasingly frustrated with his tiresome job with little benefits, whilst the criminals live a life of luxury. He is offered a undercover job to infiltrate a Triad gang led by Boss Tin (Eric Tsang). Mike slowly becomes engrossed in this world and in Tin's wife (Suki Kwan). The acting by these three actors is top notch, particularly the charismatic Eric Tsang who steals every scene he appears in. It is this acting that lifts the film from mediocrity. One of the major flaws in this film is the music. It features some syrupy ballads over the romantic moments which would seem more at home on Emmanuelle.Cop on a Mission can't really compete with other similar Asian films like Infernal Affairs (also starring Tsang), but it is enjoyable and at times is reminiscent of such classic gangster films as The Untouchables and Goodfellas (although never really matching them). It also throws up some neat twists at the end, making this a worthwhile watch.

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.
