Is Lin Chung actually supposed to be mixed/Eurasian?

Wow. First of all, you apparently just take for granted (for who knows what reason) that anyone assumes the show was filmed somewhere other than Australia. And not only that, in Hollywood no less. WTF?

They wouldn't have had to "fly someone halfway around the world" just to use a fully Asian actor or even another mixed actor who actually looked more authentic. (There are plenty of hapas out there who can pass for full Asian — Philippe Day doesn't.) You seem to be under the curious impression that Asian actors are so vanishingly rare that the show's producers would have plausibly been unable to find a single qualified person in the entirety of Australia. AUSTRALIA, of all places. A country which has one of the largest Chinese populations on Earth outside of China itself, and in which the Chinese constitute the largest non-Anglo demographic. How utterly and completely absurd.

I'm open to the possibility of a reasonable explanation for their casting choice, but that is most certainly not one.

I agree with you, I think people are nit-picking again. However, I'll point out that you've used "dearth" backwards. What you mean to say is that Australia DOES have a dearth of actors who would fit the part, while Hollywood would supposedly have lots.

But I note a bunch of (also nit-picking) people made the exact same complaint about the casting of the now-cancelled U.S. TV show "Rush Hour" with Jon Foo, a Chinese-Irish actor. Considering the martial arts fighting requirements of the character, I thought they did a admirable job.

P.S. I also thought the person who answered you previously was very rude to you, and it was quite uncalled for. But then, that's the internet for you!
