This seems to be marketed as a martial arts film, but it's really a love story with the necessary conflict and heartbreak. The kickboxing scenes are limited to ring events; arson and fights outside the ring are realistic and not cartoonish. I watched a Region 0 DVD with English subtitles; I could not tell, exactly, which audio was French, which was Chinese, which was Thai. Samuel Le Bihan sings in Thai! I read elsewhere that the Ramirez brothers are first-generation French of Spanish parents; maybe I'm a barbarian American, but I don't see where that's explained or hinted at in the film, unless it's the name "Ramirez." The actors all do a good job. A lot of the personal conflicts do not get resolved; how many do in real life? I am glad I saw this movie.

Watched this on holiday in France and it really took me by surprise as I could not read the cover on the DVD but it did have English sub-titles and that was good enough for me. Without giving the plot away, it is a brutal film and very realistic, the acting is some of the best I have seen, the storyline has many twists and turns and keeps your interest throughout the film. The family concerned in the film are a typical multi ethnic family living in the suburbs of Paris, poor but have a strong family bond. The story basically starts off when one of the brothers visited by an old rival from the past which sets off a chain of events which gets more and more catastrophic as the film goes on, different cultures clash head on. As I said this is a brilliant film and I highly recommend it, but it is brutal and the realism will startle you. Top film!
