Right now I'd have to go with "Hero", staring Jet Li. It's a bit long although I really enjoyed watching it. The film is based on an assassination attempt on the king of Qin by Jing Ke, during 227 BC (Wikipedia)
The artistic style of this movie is very beautiful, with each scene changing drastically in color and appearance. It also has a "Chinese mysticism" feel to it with warriors flying about gracefully, fighting in mid-air and deflecting arrows with meet swords (similar to crouching tiger, hidden dragon). If you can get past all that the story is pretty good, it revolves around "nameless", an unknown, insignificant prefect from a small land. He has spent years training to perfect a killing blow to strike down the king of the Qin region. The king is difficult to reach due to previous assassination attempts by broken sword, flying snow and long sky. Nameless colludes with them, collecting their broken weapons as proof of their removal in order to gain the kings trust. When he is within striking distance the king realizes his intent, a bit too late. However Nameless decides to spare him based on both broken swords request as well as the kings understanding of a picture drawn by broken sword. The picture displays the ideal warrior, one that desires peace. Nameless puts aside his desire for revenge in order to let the king unite the land in peace since only the Qin army is strong enough to pull it off. Flying snow felt betrayed, blinded by feelings of revenge, not fully understanding why her mate, broken sword convinced Nameless to abandon the attempt. She ends up striking sword down when he refuses to fight, only desiring peace.
Anyway this is just my opinion but i feel its a really great film. You should definately check it out.
