Trivia

When Yan and SP Wong are waiting at the elevator, the digital floor counter skips the 4th floor. In China and Hong Kong, the number 4 is considered bad luck because it sounds similar to the word 'death'. See more »

The Spirit of the time
4 December 2004 | by tizmothSee all my reviews

I looked over a squad of reviews and was sad not to see anyone writing from Hong Kong. So I am putting in my piece.

Hong Kong movies have changed a lot in the last decade and when Infernal Affairs came out it was a real change. I noted 'Golden Chicken' was mentioned earlier, and that sums up many of the lame comedies that have recently been churned out. However the comedy is a large part of Hong Kong cinema, as is the gangster genre.

Infernal Affairs breaks with the comedy, keeps the gangsters (lau being a first class clean cut one - whilst Leung acts a remarkable strained police officer) and adds clever and intelligent tension. The acting is first class, as is the mood that truly captures the zeitgeist.

This movie is about the two characters and their similarities and moral obstacles. It also has something subtle to say.

This film was huge news in Hong Kong and the mainland. It is an important Hong Kong film.

The US remake will be more clichéd than you can imagine. This film will translate, it is not that original, no. But it has substance and mood that is valuable.

See it.
