"Infernal Affairs III" will be shown in December. There were many different versions of rumours about the story of this movie. The identity of "Yeung Kam Wing", played by Leon, a senior superintendent in the Security Department, had been rumoured to be many different versions. Some reports pointed that he was the same as Andy Lau, a spy sent into the police force by Eric Tsang, but some reports said that he was a spy sent into the triads by the police, but later he was sent back to the police force as the triad's spy, he was a "Double Spy". However, the director Andrew Lau said that all the rumoured storyline and ending were not accurate, and you would only know Leon's true identity at the end of the movie.

Can't wait to see this show, look like LEon is the main character of the movie.

looks like leon plays a super duper crucial character!! =)

I was translating an article for this forum and 1/3 way through it I stopped. It sounded he is crucial in this movie with Andy Lau trying to play against each other, uncovering each other's identity.

I don't want to know more, so I stopped translating.

Watch the movie guys.
