Spotted this posting over at Entertainment Weekly's PopWatch Blog: Calling the bluff: Is '21' racist? This entry over at the movie blog Cinematical debates the issue of 21 and the "screwed-up Hollywood movie-making process": Discuss: Is '21' Racist for Changing the Ethnicities of Its Characters? The ensuing discussions in both blogs are pretty interesting, a few bonehead comments aside. At least people are talking about it.
Also worth checking out is this op-ed piece in MIT's paper by Alvin Lin, one of the most vocal opponents of 21 since this whole uproar started: '21' Discriminatory Casting Unjustified. If any good can come of this, in any case, it has people scrutinizing what we all know Hollywood does on a regular basisexcluding Asians from the process. While the movie was number one at the box office last weekend, I doubt it'll stay on top for long. Harold and Kumar is coming.
