Above is an image of Heimdall (played by Idris Elba), from “Thor”. Some in the fan community were incensed when they found that Mr. Elba would be playing Heimdall because the character–as designed by Marvel–is white (image below the break).
Idris Elba, a character actor with leading man looks, commented upon the matter to Hero Complex. His view is, if a black person playing the role bothers someone that much, then don’t see the movie.
Frustration with the hiring of Mr. Elba by Kenneth Branagh (the director of “Thor”) has resulted in the formation of websites like Boycott Thor, which lays out the case as to why he should not play the role.
The largest problem that those that wish that Mr. Elba was not cast is that the comic that the film is based upon isn’t a strict interpretation of Norse mythology. The names are the same (Thor, Odin, Sif, etc) but little else closely follows Norse myth–except in the broadest of terms.
So, as far as this screenPhile is concerned, Idris Elba is a great actor (check out “Luther” or “The Wire” if you get the chance. Mr. Elba is brilliant in both) and can only bring a typically great performance to “Thor”.
