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 »

I like it better than Martin Scorscese's remake:
28 February 2007 | by See all my reviews

After I enjoyed Martin Scorcese's "The Departed, I decided to watch the film that inspired the celebrated director to re-make it and move the action from Hong Kong to Boston, MA, USA. I must say that I liked the original movie better: 50 minutes shorter than Scorcese's magnificent remake, "Infernal Affairs" is tighter, faster, more compelling and tells the same story better. It does not have a grand acting Jack Nicholson who basically plays Daryl Van Horne with the attitude and "Infernal Affairs" characters don't talk and don't curse as much as they do in "The Departed" but the Hong Kong's movie only benefits from it. As much as I admire Leonardo DiCaprio as Bill Castigan, Tony Leung (Yan) in his role is simply unforgettable.
