Shi mian mai fu
I saw Zhang Yimou's House of Flying Daggers on Saturday. If you liked Hero, then you will probably like this one a little better. Ther story is a bit more tight. If you hated Hero, then I don't know what you would think of this one.
Again, it has beautiful cinimatography. Again, the plot has twists and turns. I liked Ziyi Zhang's performace in this one a lot.
