Um, did the script call for "caucasian leader of Shield", and they put Sam Jackson in the role? Nick Fury is not DEFINED by his race. Neither is the Kingpin (who is defined by his FAT), or those other parts actually telling a story in which the race of the character is a defining feature? (Was being Jamaican, for example a necessary part of the role?)
In "Aloha", the core idea of the part IS the race. That's the dramatic intent of the whole thing. When you CHANGE that dramatic intent, and put someone who isn't that race into that role when you don't HAVE to make that change, I think it's a little eyebrow-raising. When the part is specifically about the character's race, you should at least TRY to put someone OF that race in the role.
Can you do "Guess Who's Coming to Dinner?" with a white man in Sidney Poitier's role? OF COURSE NOT, it blows the entire point of the show, because the entire plot rotates about the fact that this white girl has brought the man she loves (who happens to be black) home to her straitlaced WASP family.
We've secretly replaced the coffee in this upscale and trendy coffee house with Chai Tea... Let's watch the fun!
If the POINT of the movie is for the lead character to be Asian, then the actress should be Asian. Or at least they should have tried to find an Asian actress first, before jumping on the blue-eyed white girl.
I mean, Rock Hudson could have acted the part of Dr. John Prentice with his eyes closed...but it would have sort of messed up the plot if Joanna shows up at home with a white guy. If the parents still act shocked, WHY WOULD THEY? Were they expecting a black man? Maybe they thought she was a lesbian, and are shocked she's with a man at all? (Though to be fair, Rock Hudson WAS gay...)
Come on. When the part is specifically ABOUT race, fill the role with someone OF that race. Can you cast John Buscemi as Malcolm X? He's a fantastic actor, but the whole point of Malcolm X's story is that he's black!
Nick Fury could be played by Sonny Chiba and it wouldn't matter to the ROLE.
