I like how the thread starter mentions the example of utter hypocrisy this issue brings up in a complete handwaving motion.
When The Last Airbender cast was announced, there were dozens of online petitions and websites put up declaring that the movie was racist because much of the cast was white.
Ignoring that it was cast by a man of Indian descent.
Ignoring that the characters in question all had blue eyes in the cartoon.
Ignoring that the cartoon was not set on Earth, and so there were no such terms as "Inuit" or "Caucasian" to begin with.
Still, there was tons of protest and hand-wringing, and oh that racist racist white... M. Night Shymalan!
Here, the reverse happens, and you have the audacity to call the people complaining racist? Why didn't you level these complaints at those protesting The Last Airbender you damned hypocrite? You disgust me.
And to the gaggle of idiots replying to this with "OMG HE WAS AWESOME" "IT WAS SO EPIC" "HE WAS DA ONLY THING I LIKED HURF DURF" I think you've completely and utterly missed the point on pretty much every single level.
There were no black Norsemen. Heimdall was white in the comic, and in the actual mythology is the "whitest of the gods" That's you know, his title. In a pantheon where someone having black hair was enough for them to be "the black".
And yes, there was one single comic where Heimdall was black, but it took place in an out of canon separate universe, and was written after the movie started filming, not 616 or Ultimate.
And yes, I was offended by Samuel L. Jackson being cast as Nick Fury, mostly because I utterly hated the Ultimate universe. I also take issue with the utterly shit costume design for Captain America and the fact that it's in the script that he's written as hating his comic book costume. I've also taken issue with every single shitty X-Men movie Fox as vomited at us, and in particular despise Bryan Singer.
Did I mention I'm Hispanic? Before someone screeches racism like a howler monkey.
If you're going to stray from the source material, there's no point in the adaptation at all, because it isn't the same story. It's a different, Hollywood story with the name of something people like. It's cheap, it's crass, and it's disgusting. Every single time. It's like putting out an ad that you're selling a Porsche, but when buyers show up they're greeted with an olive green Pinto with the word "PORSCHE" spray painted on the side. Hollywood doesn't make good movies, why should we ever trust a single decision they make?
Also, no one thinks it's a completely asinine argument to make that it's okay to switch a character's race because there's magic and space aliens involved? Would the same convention apply to the supremely magical Monkey King from Journey to the West?
