On his Twitter, producer Frank Marshall continues to deny the production has discriminated by giving opportunities for actors of color to white performers. After a series of twitters back and forth between angry fans and himself, Marshall made his final comment on the subject last week saying, "The casting is complete and we did not discriminate against anyone," defensively adding, "I am done talking about it."
Yyyyyyeah, see, that's not how it works. If you do something racist and then declare it to not be racist, it's, uh, actually still racist. Sorry 'bout that.
(A brief moment of disclosure: I haven't even watched Avatar yet; been meaning to get to it, haven't gotten to it. And I would have been ignoring the movie version, because theatrical live-action adaptations of original animated works almost uniformly wind up as fetid piles of donkey shit. Alas, Paramount is making this particular pile rather impossible to ignore.)
