What I meant was that if you're going to make a movie that's basically set in Asia, you should probably cast Asians in it. The wonky part is that they're casting White people to play characters that are meant to be Asian. If that was not made explicit in the cartoon itself, then the fact that they are using Asian extras to play those characters' family members is clearly a sign enough. And that smacks of the grand old Hollywood tradition of Yellowface.

And like I said, I'm pretty sure they could have found Asian actors. I'm not an expert on the casting process, but I'm sure they could have done it if they really wanted to. I am willing to bet that none of these kids are going to win any Oscars for their mad acting skillz.
