Historically speaking, animating female characters are really, really difficult, ‘cause they have to go through these range of emotions, but they’re very, very — you have to keep them pretty and they’re very sensitive to — you can get them off a model very quickly. So, having a film with two hero female characters was really tough, and having them both in the scene and look very different if they’re echoing the same expression; that Elsa looking angry looks different from Anna (Kristen Bell) being angry.
So that’s their (blatantly misogynistic) excuse for scrapping all but two of the female characters; that they’re too hard to animate? Those emotional female characters, they’re all the same, right? Here’s a hint: their “femaleness” isn’t what’s making them indistinguishable.
Animation is an intricate and complex art form. These comments were recklessly taken out of context. As part of a roundtable discussion the binaries was describing some technical aspects of CG animation and not making a general comment on animations females versus males or other characters.
