I have watched several Asian movies that did not feature a single American actor, and I enjoyed them. My favorite is Hero with Jet Li. That was an awesome movie!
I’m not sure why our people would think that they have to cast an Asian in order to attract an Asian viewer. It’s the subject matter of a movie and sometimes the talent of the actors that attracts me, not the “diversity” of the cast.
I had seen another movie on Netflix or Amazon a while back. It was a horror movie shot in Hong Kong or maybe Korea, I’m not sure, but all of the main cast was American, and I was like WTF, they are so out of place in this movie. Why film there if you’re going to feature Americans? I don’t get it.
I enjoy KDramas, and frankly, I don’t want to see Americans in them.
