I saw Malaysians and Singaporeans basically lashed out against an American on Twitter for stating Golding is white passing since he's half white which is the reason why he even got the role. Thing is he doesn't actually look white, he looks exactly like your local South East Asian person and I am saying this as someone from the SEA. Then there is Simu Liu who stated that he lost the Nick Young role because he doesn't have the "It" factor which reminded me on Brenda Song who whined that they didn't even call her to audition. Seems like the director Jon M Chu, who is Asian American of Chinese heritage, didn't think Liu or Song is good for the role and that's about it.
But I am curious, especially those in the west, does Golding like not look Asian enough for you?
