I don't know if the story per se would change, all of the elements could remain, but, I think the meaning of the story would change. Which I think is interesting--and I think using stories that reflect the era in which we are in, rather than when the story/character was created, is important. It's why we don't perform Shakespeare the exact way as it was done centuries ago. We find new things and new meanings that talk about now.
Yeah, but again, the audience obviously wants a more traditional Superman, as the bad reactions to the Snyder movies and the positive reactions to JL's Superman (though not so much the movie as a whole) have shown. Also, as
@Christopher has brought up, other black heroes do exist. I'd love to see a movie adaptation of Icon. Or a TV show of Icon. Or a new comic series for Icon. Or reprints of the original Icon book. What I'm saying is, GET YOUR SHIT TOGETHER, DC AND MILESTONE, I WANT ME SOME ICON!!!
As far as how much it would change the character himself,
@Christopher mentioned the public's reaction to a black Superman as opposed to a white Superman. There's also him growing up in small-town Kansas. Now, as a German, I can't say I have much experience on a black kid growing up in rural Kansas, but it would be my guess it would be a very different experience from white kid.
That said, WB would never do it... at least not in the next few decades. As much as people want to believe it, Hollywood is conservative by nature, they are a business first. There would be panic in the halls: "how are we going to have synergy with all of the games and toys and comics and t-shirts!? How will we sell the brand!? Oh, and yeah, the internet."
There's also the problem with the Chinese market. I've read reports about racism against black people being far more wide-spread in China. To get more than 100 million at the Chinese Box Office for Black Panther, Disney
had to modify the marketing, emphasizing the mask in the visual marketing in order to hide the character's ethnicity. The Chinese market is also the main reason why homosexuals don't show up openly in big blockbusters, as the Chinese censors won't allow movies adressing homosexuality into their market.
Bats is one of the few comic book characters who I would argue has to be white because of this very reason. He comes from Old Entitled Money. In some ways he's rebelling against that, and in other ways he's embracing it (Batman: rather than getting therapy and donating billions to help solve the problems, I, ALONE, will solve it.)
Though it might be possible to have Batman be bi-racial, with white Old Money Thomas Wayne having married a black Martha (though the Batwoman fans who demand the character be Jewish would cry bloody murder on that one).
I would also agree with this. As far as movie Bond, for the most part, his family history hasn't played much into the franchise, save for 2 or 3 movies--ugh, Spectre-- it might be different for the books.
The books didn't adress his family history much beyond the small bit in "On Her Majesty's Secret Service", but as I stated, Bond's family history isn't at all a hindrance in making Bond black, as there has been a black minority in Great Britain for about a millennium.
I am sort of surprised, and not, that Salt didn't do more. I think it's a really fine thriller and Jolie feels credible as an action star. But, I also suspect, she wasn't super interested in pursuing it, as she has other ambitions than being an action star.
"Salt" wasn't that profitable for the studio, but I think that has more to do with the plot being a bit derivative of the Jason Bourne movies than with Jolie. A sequel with a more original plot (or a more classic spy-fi plot á la classic Bond) would have done better, I guess.
When it comes to box office, female spies haven't had much success even lately, although it might be a problem that a lot of them ("Spy", "The Spy Who Dumped Me") have been played for laughs or been more drama than action thriller ("Red Sparrow". Let's hope for the "Black WIdow" movie.
