Only the main character? There's no one in that movie that isn't a white Brit, as far as I can tell (save Gyllenhaal, who is a white American).

Anyway, back to the main post... I hate the idea that audiences couldn't connect to non-white characters because HOLY SHIT, THEY ALREADY DID!!! THIS IS WHY THE MOVIE WAS FUCKING WELL OPTIONED, BECAUSE THE SERIES WAS POPULAR AS SHIT!!! *rageface*

*ahem* My point is, it makes my brain hurt.

(And I don't even like Avatar. But this fills me with rage.)
