Trivia

The English title is a play on words mixing Ming's job in the IA, the infernal nature of both characters' double lives, and finally Dante's Inferno, relating to the original Cantonese title. See more »

Goofs

When Lau goes to listen to the "sampler" CD that's been dropped off for him, he presses the button on the player and we see the CD drawer close twice - first in the long-shot, and then in a close-up that starts from a fully-open position on the drawer. See more »

One of the better cop movies
7 October 2003 | by (Melbourne, Australia) – See all my reviews

  • Infernal Affairs: 9/10




A brilliant cop movie out of Hong Kong, with a sublime plot and great acting by the two leads Andy Lau and Tony Leung (an indescribably great actor). An amazing concept with Lau as an undercover Triad member in the police force and Leung as an undercover cop in the Triad... which leads to many interesting situations. Great stuff, and the DVD even has the alternative ending (which isn't nearly as good as the main one).
