I am half joking. I grew up in New England, and I personally was surprised when some of my Portuguese friends considered themselves non-white. I guess I hadn't thought that they were "other" And was also surprised that many Italians felt the same way! Especially since their parents had been the "other."I know you’re half joking, but it’s not like she isn’t still being played by someone with a light complexion.
To accurately portray Snow White you would probably have to find a better looking Tilda Swindon and dye her hair black. I am not saying that Tilda is in anyway ugly, just that she would probably not qualify as the "fairest of us all."
