Internal Affairs is a deliciously twisted thriller from Hong Kong. Go to Full Review David Ansen Newsweek 03/13/2018
The pace and plot are dizzying, but the movie also works as a study of fractured identity: the two have led double lives so long they're no longer sure who they are. Go to Full Review Nick Schager Lessons of Darkness 05/04/2005

Sammer A @sammer864 Feb 15 The Prefect movie of it's genre. See more Isa B @RT32418990 Jul 11 For many American film fans, this picture will always be compared to Martin Scorsese's The Departed. After all, this was the material from which the screenplay for The Departed was developed. With a shorter runtime, this film is faster paced. Of course, I could be a bit biased because it's Martin Scorsese and I saw The Departed first, but I do believe it to be the better of the two films. Martin Scorsese and his brilliant cast just did it better, plain and simple. Judging Internal Affairs by its own merit, it is absolutely a great film. I most definitely recommend it. 92/100 See more S R @ScottR 04/01/2025 Definitely one of the better cop thrillers from Hong Kong. However, Hollywood took this and made "The Departed" that was so much better. This had some odd parts that didn't make sense, but it still was entertaining. However, I don't plan to see it again. I saw it since it was on the NYT 1000 movies list. SLC DVD. See more Leprechaun K @LeprechaunKing 02/26/2025 Original and captivating. Well written, well acted, and well directed, with a fantastic score. No complains. See more Insomniac X @RT03001349 02/02/2025 This slickly produced police thriller is far more stoic than its American counterpart, but just as tightly plotted. The film's subdued emotional pitch ultimately undermines some of its suspense, despite an abundance of clever twists and turns. See more ChrisCSH H @RT12343453 01/27/2025 Infernal affairs is a thriller of a Hong Kong cop movie some good espionage mixed in with some old-fashioned noir with a incredible ending scene.
