Charlie Chan was played by white guys but that doesn't mean Hollywood should make a modern Charlie Chan movie and cast Cumberbatch in the role.
Chan was stated on many occasions to be Chinese.
Khan's actual background was never stated. There is one line of dialogue - using words like "probably" - in which McGivers speculates
on his ethnicity. That's it. As far as racebending goes, this one's a non-starter, sorry.
