剧情介绍
孔武有力的夏侯武（甄子丹 饰）曾是佛山武馆合一门的弟子，当年他争强好胜，在香港担任教官时与他人比武，结果失手将对方打死最终锒铛入狱。三年后的某天，闹市街头发生一宗离奇车祸，死者似乎在车祸前就被武功高强之人残忍杀害。夏侯武在狱中看到该新闻，心知在此背后有一场针对武林中人的猎杀正有条不紊地展开。他强烈要求面见重案组总督察陆玄心（杨采妮 饰），由于言中接下来命案的遇害者，终于取得陆督察的信任，得以协助警方办案。与此同时，先天残疾却练得一身绝技的封于修（王宝强 饰）四处挑战隐于闹市的高手，更在获胜后将他们无情杀害。
武林波涛汹涌，夏侯武和封于修迎来对决的终极时刻…… A vicious killer named Fung goes around Hong Kong killing top martial arts exponents and leaving a secret weapon called the Moonshadow as his calling card. When a convicted killer and kung fu expert named Ha - formerly working as a martial arts instructor before accidentally killing a man and being imprisoned and convicted for the crime he didn't intend to do - hears of this, he offers to help the police catch the killer in return for his freedom. With Ha's help, the police realize from the chronological order of the victims that the killer is targeting his victims, all top masters in their respective martial arts style, and following a martial code of training. After a close encounter with Fung, Ha suddenly disappears and the police begin to suspect the worse: that the two are accomplices and Fung was the bait to help spring Ha from jail. But Ha has actually gone back to his home in Foshan to find out more about the mysterious calling card. While doing so, he discovers the killer's identity and his motivation: the true philosophy behind Fung's martial arts is to kill opponents who are weaker than him. Steadfastly, Ha refuses to be drawn into a fight with Fung - until the killer threatens the woman he loves most. Only then does he realize that he would have to go against the martial code in order to uphold it.

打的这么好看，你们还想怎么样？总是用剧情片的标准去要求动作片，你丫有病啊
虽然对国产电影没抱多大希望，但看完之后，我只想说，剧情有没有那么烂好么？而且动作戏也相当精彩，王宝强的表现很意外，格外加一星。打一星的我真想说你们看了么？没看过就在这儿瞎BB，对人不对电影，我特么的真是醉了。只是整成3D完全没必要，太坑钱了，成都这边电影院排片好少，一天就三四场！！！
拳拳到肉 非常过瘾!导火线之后成了丹哥铁粉，什么赵文卓的通通懒理。只知道一有丹哥的电影必须去看，虽然去年冰封侠确实很瞎，但丹哥欺我上千遍，我却只记导火线!毕竟丹哥的年纪不小了，只知道在这个特效横飞的年代，如此良心的打斗太难得，恐怕是看一部少一部了。结尾的字幕我这个非功夫片迷都有点小
拉高下分数，虽然没剧情，但是打斗戏精彩，不至于一分，而且公路上的打斗很有新意，刺激。
现在真的很难看到这么纯粹的动作片了。虽然那个神马师妹是来闹场的。另外甄子丹你负责打架就好了，不要负责耍帅，方中信出来三秒钟就把你秒到外太空了。
一部向香港动作片黄金时代致敬的诚意之作，启用了动作片台前幕后的工作人员，最大的亮点，邹文怀啊，嘉禾的老板，有木有，独臂刀啊，孟海，姜大卫啊，感动
我得强烈推荐一下，动作戏又多又好看，高潮甄子丹和王宝强在高速路上打，大卡车来来回回，不像其他动作片都是在毫无干扰的“真空”环境打，格外紧张刺激，快速，连击，密不透风，酣畅淋漓
好看，王宝强演的也不错，甄子丹更不用说，是一部非常值得看第二遍的片子。装逼挑刺的喷子们可以滚了
不得不说子丹大哥成功雪洗了之前《冰封侠》和《特殊身份》的耻辱！一部功夫片兼警匪片完美结合，拳打脚踢擒拿兵器各路集聚，动作设计相当精彩，打斗场面爽到极点！宝强饰演的疯子逼真的要命，白冰的美艳气质回味悠长，各路动作影星大打出手，对那些没看过就打低分黑甄子丹的人来说，真是错过了一部佳作
虽然王宝强有点让人出戏，不过动作戏还是很赞~ 这次最后的打斗武打设计不错~那些黑子直接不看片直接给1星的，自己删耳光吧~
两星半。其实很喜欢这种设定，当代背景的江湖与武林。不过剧情编排太平庸了，很多地方可以再商榷，起码现有的剧情吸引力不大，悬念也不足 。同时，王宝强不适合这个角色，因为他真的只适合一类角色，而这种太邪太恶的角色总觉得很搞笑，让人很难严肃起来。
反正打的过瘾
《一个人的武林》，导火线之后，甄子丹自己都无法超越的电影，近几年最劲的功夫片，集齐了N多老武指，片尾特别鸣谢里有苏照斌，也就是说剧本是请了剧本医生的，王宝强的融入感还算可以，没跳戏。
你们都是在给冰封打分不是这部。。。。。。。。。。一星的什么心态
这片子最失败地方是选角傻根
