I watched the film on UK channel cnx some time between 2002 and 2003 and I believe it was in korean.
The parts of the film I remember are fairly vague and distant, but it was over 10 years ago when i watched the film.
I remember at the beginning a big fight scene involving two gangs, at the end of the fight scene the protagonist of the film was stabbed with a knife which had 3 separate blades. The film then flashed forward a few years and showed the protagonist of the film with a limp. The last thing i remember of the film was the protagonist meeting a man and a girl at a cafe. I believe the girl was his daughter because they could both roll their tongues (the other man made a big deal of this).
