I think Elba will be great and Heimdall is not very well known anyway, so it will be fine. I personally have no problem with it.
I wonder if everyone calling people "racist" over complaining that Heimdall is black would have a problem if Bishop, Luke Cage, or Black Panther were cast as white? I would like those guys to be black personally. That doesn't make me racist.
I'm in the "if they are not that well known then its not that big of a deal" camp. You can change the race of minor characters with little break in the suspension of disbelief but its harder to do with major ones and should generally be avoided IMO. Its not about race either, its about adhering to the source material. It would annoy me if Wasp was a man.
It would also annoy me if Thor was a 5'5 guy with black hair or Captain America had a french accent.
It doesn't make me prejudice, racist, sexist or anything else. Just a geek![]()
