Another case where race-altering in movies may have had unforeseen results if one were to delve beneath the surface:
The abomination that has come to be known as
Fant4stic (2015).
We could assume they changed the Human Torch's ethnicity for whatever reason, but he was a character with relatives in the movie which made explanations for his sibling being a different color a bit more complicated than necessary.
Traditionally the Human Torch (Johnny Storm) was the younger brother of the Invisible Girl (Sue Storm) - to emphasize this fact they were both depicted with the same blond hair and blue eyes.
But for this particular movie they chose a black actor to play Johnny and a white actress to play Sue. And it wasn't a case of they chose an actor who happened to be black to play a character supposed to be white, but a whole narrative was written around this Johnny's ethnicity because his biological father, Dr. Franklin Storm, was a significant part of the story and he was also black.
The official backstory for this movie version to explain why Johnny & Sue were different ethnicities was that Johnny's parents, (the Storm's), were black - they adopted Sue (a white orphan) when she was an infant and Johnny was their natural child.
So what, you ask? At the time I did a little research on orphan & adoption statistics - I don't remember the exact numbers, but the facts were that white infants are something of a commodity (to white parents seeking to adopt) - there are often waiting lists for white infants. Conversely, a sad fact is that black orphans far outnumber white ones and thus go without families at a far greater rate than white orphans that are more readily adopted. Orphanages are desperate for anyone to adopt black children.
So, with that in mind, let's consider Dr. Storm and his wife - he's a renown scientist and well-to-do. But instead of he and his wife adopting one of thousands of black infants that need a home they adopt a white orphan! Is this what a black couple seeking to provide an orphan child with a home would do?
What are the odds that a wealthy black couple seeking to adopt would choose a white child (who we know has far greater prospects for adoption & would probably be on a waiting list for wealthy white parents) over their pick of thousands of black children they could provide a future for when orphanages are desperate to find homes for black orphans?
The whole scenario rang ridiculous... and all this complicated confusion surrounding a backstory that never had to exist just to force a race change to a major character?
Heck, it would've been easier to just have Reed (Mr. Fantastic) or Ben (the Thing) or even Victor (Dr. Doom) played by a black actor since none of them had any family connections as major characters in the movie.
In the overall scope, the race-altering ended up being the LEAST of this movie's problems - to Marvel fans, this movie was sheer blasphemy on every level and made its 3 predecessor films look like classics!
