Inside hau s organization , yan befriends keung chapman to , one of sam s underlings . meanwhile , in order to strengthen his position , sam has sent a young subordinate ming edison chen ; adult character played by andy lau in infernal affairs to enroll in the police cadet academy 两人分别依靠卧底刘建明陈冠希饰及陈永仁余文乐饰的帮助，在黑帮及警局内扶摇直上，并合力对付头家族首领倪永孝吴镇宇饰。
His character is the representative of hong kong cinema . the way he is being attacked by shawn yu for ten years parallels to the fact that hong kong movies are being " attacked " by local movie critics and audience for a long time since the decadence of the hong kong film industry in the mid 1990s 他被日弹夜弹，弹足十年，正如港片自九十年代开始衰落，被观众和影评口诛笔伐，日弹夜弹，但是还健在，仍然没有死去。余文乐代表的是观众。
They , together with hau francis ng , the boss of the mafia family , are the focus of the movie , while the original lead in the first movie , yan shawn yue and ming edison chen , the young version of tony leung and andy lau respectively , are placed at a subordinate position this time 从片头字幕的演员排位中可以看出，影片真正集中描写的，是黄sir和韩琛两人的关系，加上黑帮头倪永孝吴镇宇的介入，少年版刘健明和陈永仁陈冠希和余文乐的戏份著实不多。
New director wong ching - po is never afraid of experimenting with new effects to enrich his cinematic language . exotic camera angles are used wisely in many scenes , for instance , " the transparent ground " where turbo edison chen is beaten and " andy lau s moving table " in the restaurant are among those notable examples 故事比较特异之处自是主角洪仁就刘德华和左手张学友以外的一条相对发展的支线即社团新手翼仔余文乐和turbo陈冠希的发迹史。
He plays the role of a cid who always wants to transfer to the sdu department . he does get into the sdu training camp that is headed by michael wong , but the training session only takes up a small part of the movie , most of the remaining plot is reserved for yu s investigation of an armed robbery case with patrick tam as the primary suspect 本片主角是余文乐，他饰演满心希望进入飞虎队的警员，亦有跟随王敏德这个飞虎教官训练，但这只不过是电影的一个小段落，剧情的重心不是这套训练，而是余文乐调查的一单抢劫案。
It is something that makes you feel comfortable to watch , i was surprised to see how joe ma has totally subverted the usual play boy image of yu and turned him into an innocent and cute young man . nonetheless , one disappointment is that none of these sub - plots tend to work together as a whole . they function well in their respective moments , but when they are put together , they just don t seem to look very coherent or actually help the plot to advance smoothly 个别场面都拍出一定的吸引力，陈小春在蔡卓妍、周丽淇、余文乐甚至韩君婷等人之间周旋，演得尤其落力，但整体来说几段支节始终制造不出连成一线的剧力，不少场面如余周大闹日本歌坛教父的家或陈小春夜闯韩君婷香闰等都来得零碎，顶多只能博得观众一灿吧了。
The two of them rarely talk but their postures alone already bring out the uniqueness of their characters . talking about yan and ming , the supposedly major characters of this series , it is certainly meaningless to compare shawn yue and edison chen with tony leung and andy lau , but you can feel how much effort they have spent on imitating their predecessors . to sum it up , 两个少年版陈冠希和余文乐算是演得投入，虽然很难相信一个人的面孔在三数年间会有这么大的转变无ii在1997年完结，无的故事应当发生在2002 03年左右，但两人的努力模仿已经勉强合格。
The plot suffers from serious illogicality , some scenes just don t make much sense , for instance , if the priority of the gangs is money ( as they have spent so much time to conceive their " fake note " plot " , when do they keep luring and taunting with the police and sdu ? if patrick tam is such a brilliant guy , why would he want to team up with the mad white guy who always wants to challenge the cops ? shawn yu s showtime at the end also ruins the team spirit of sdu as promoted in the beginning 虽然此片有让人看得投入的地方，但编导在剧情上却施展了太多掩眼法，细看之下会发觉不少情节都不太合理，例如匪徒既然为钱，谭耀文又是所谓的智能型罪犯，多番把飞虎队引蛇出洞的行为便极不合理兼多馀；飞虎队一向主张团结精神，但电影到了最后却变了余文乐的个人表演，也大大破坏他之前建立起的血肉型像。
