Round 2
Crouching Tiger, Hidden Dragon (2000) - Yú Xiùlián vs. Yù Jiāolóng
Yù Jiāolóng (Zhang Ziyi), the daughter of a rich family who is being forced to marry into another rich family, shows admiration for the life of Yú Xiùlián (Michelle Yeoh) because of the freedom she has to live the way she wants. But their connection breaks down when the spoiled Jiāolóng, referred to as Jen in the English version, becomes angry at Xiùlián (romanized as Shu Lien) for lecturing her and challenges her to fight.
The numerous weapons Shu Lien uses are specifically designed to combat swords but they fail despite this. The diverse weapondry keeps the fight fresh and interesting while demonstrating Yeoh’s abilities with each one. The fantastic fight choreography has a rhythm that is almost hypnotic and the ambience creates a perfect atmosphere for a one on one battle. While many American fight scenes tend to be a bit gimmicky when it comes to editing and cinematography, this scene is very conventionally edited and uses mostly practical effects which make the performances by both even more impressive.
What’s also extraordinary is the preparation both actors put in. While Yeoh had been starring in martial arts films for over a decade prior to Crouching Tiger, Hidden Dragon, she did not speak Mandarin. This meant that she needed to learn Mandarin to play the role. Meanwhile, Ziyi spoke Mandarin but was a professional dancer by practice and had never been in a martial arts movie. This meant that she needed to learn swordplay prior to the movie to the point where she could shoot scenes such as these for the film.
It’s those reasons that one can use to make a case for this being the best fight scene of all-time even over Oldboy.
