Well if Tom Hiddleston can deny a likeness approval (as we were told by HT), then I am pretty sure ScarJo can do that and probably more. Besides the hair issue can easily be read as one of likeness not "materials". The doll hair looks more realistic when done well to many people (myself included). Add in that doll hair is what the vast majority of women expect on a doll and you have a reason for an actress (or her underlings) to make that request.
That's great and all, but once the figure gets in-hand, and it doesn't look like the prototype does, and the color is wrong ( again) I think many people will change their tunes.
And It's NOT going to look like the prototype once people get her in hand. Yes, babydoll looks pretty good. but her style is two pigtails, and straight hair. it's kinda hard to screw that up. Widow's hair has a distinctive look and style. and it's going to be close to impossible to make it look like that after being packed in a box for 8+ weeks. For that matter, if you look at the pictures of it in the case at toy hunters, her hair is ALREADY starting to frizz a little, and come out of the styling.
Sokay. Perhaps we will get swappable hair, perhaps not. if not, perhaps a sculptor can be commissioned to MAKEa sculpted wig for her.
At the very least, the doll hair is already on a "wig" that is already removable from the head. so Sculpting a plastic " wig" is not going to be TOOO hard.
Still, the simple fact that I'm even contemplating having to do this is, in my opinion, pretty piss poor for a nearly 200$ collectable.
