I'm African American too, and don't bring up what's happened to Black and Native Americans being played by Caucasians. That hasn't happened in decades. I do understand that other races have the same problem. I really hated the casting for Prince of Persia and felt it was wrong. Where was the big controversy there?
I brought up blacks and Native American characters being played by white actors to show that Hollywood had a history of doing this kind of thing.
But that's the thing, there is no concrete proof that the characters of Avatar non-white. If anything, the only castings I was the least iffy about were the water tribe castings, but I wasn't too bothered about it. Like I said in a previous post, I don't feel like the show's creators even put up a fight against the casting. I believe the feeling is that they were deadset on finding the best actors for the roles (and in this case, especially of Ang, Sokka, and Zuko, they did imo).
Maybe the reason why the shows creators didn't put up a fight is because they knew they couldn't win the fight and that they could risk being branded as being "troublemakers" and being blacklisted within the industry. The voice actor who voiced Zuko in the TV series did criticize the casting decisions.
Hell, the director is Indian and "claimed" to be a fan of the show. Racebenders love to say that he probably didn't have control over casting, but that's BS too. He's the director, writer, and (most importantly) producer of the film! He definitely had control over casting and casted who he felt was best suited for the role.
Considering that his last several films have been flops, I don't think that M Night can throw his weight around. However, he has gone on record as saying that he did look for the best actors to play the roles, but that still doesn't make the casting right.
And about John Carpenter. I've seen too different documentaries about directors that focused on him on Reels Channel (The Directors and Hollywood's best directors) and I've never heard him mention that or any mention of it. Do you have any proof that this ever happened?
I can't recall where I've seen the interview about BTILC where they talked about the studio have a problem with the casting of Asian actors in the Asian roles. If I ever come across the interview are post a link.
