Well, Matt Damon is playing the other mole - Ming, though I think he would have worked as Yan, too. I can't really think of anyone else with the kind of presence of either Andy Lau or Tony Leung. But like I said, I am really biased.

I was wondering about the ending, since there's an alternate one on the DVD.

Oh, and it looks like there's two Asian guys in there, so I think the HK triad might be one of the Irish gang's clients.
