You can "Westernize" the story if you want, but at that point it is no longer Ghost In The Shell because the story is simply not Western.

I REALLY like Scarlett Johansson. She'll do great in Ghost in the Shell. But it bothers me Hollywood STILL overlooks a lot of Asian actors.

Ghost in the Shell was one of the most important movies to my brother and me growing up. It really does hurt to see it get this treatment.

The term to describe this move is "whitewashing" (casting white actors in non-white character roles) and there has been many calls for Hollywood to stop overlooking actors based on their race. 

Sadly, this isn’t the first time that Asian characters are completely Westernised and replaced by white actors and actresses. Take a look at some below:

Avatar: The Last Airbender movie cast white actors for its main leads

Emma Stone as Allison Ng in Aloha, who's supposed to be of Chinese and Hawaiian descent

Justin Chatwin as Goku in Dragonball: Evolution

We doubt any Dragon Ball fans would acknowledge this movie's existence. (Image: www.wikipedia.com)

Rooney Mara as Tiger Lily in Pan

Jim Sturgess as Hae-Joo Chang in Cloud Atlas

Anyway, we hope that this ridiculous tradition goes away for good, and that the movie industry stop turning the other way when it comes to representing actors of colour. 

We recommend watching John Oliver's commentary on whitewashing to understand more about the issue (and get some laughs from it).
