美国版《无间道》这部好看的娱乐片就是经典,不仅剪辑好，音乐好，剧本好，还有好多演技派大腕。台词更是经典。虽然长达两个半小时的剧情，看完后还是不过瘾。尤其是Leonardo DiCaprio 的演技见长，有望今年拿到奥斯卡。
Costello ( Jack Nicholson）: "I don't want to be a product of my environment, I want my environment to be a product of me."
Costello: "When I was your age, they used to say you could become cops or criminals, What I'm saying is this: When you're facing a loaded gun, what's the difference?"
Dignam (Mark Wahlberg ):My theory on feds is they're like mushrooms -- feed them shit and keep them in the dark.
Queenan (Martin Sheen ): We are doing everything in our power to keep YOU safe, Billy. We need the right timto nail Costello!
（我们已经尽全力在保护你了，Billy. 我们在等待时机才能搞定Costello! ）
Billy Costigan (Leonardo DiCaprio): Bullshit! What the fuck are you fucking waiting for? Honestly, do you want him to chop me up and feed me to the fucking poor?
Ellerby (Alec Baldwin ）：You got the job because you have immaculate record. Some people don't like immaculate record. I do. I'm immaculate.
