"We broke her into
seven changes. We start when we first see her she has no idea
that there's any threat to her world ... She's in a beautiful
state of ice, she's in her sleigh, she's in the snow. We move
the second time to the dungeon. In the dungeon, her dress
fills out into what we call the full monte and changes into
exactly the environment of her castle.
And as the children enter,
and as her power starts to disappear, we start to see her
whole sillhouette melt and her colors get grayer, and she
starts to lose her crown. It's about 50% now. And, from there
we go to the white witch's camp, and her dress is completely
bottom-heavy. It's gone into a deeper gray smoke-color, and
her crown is smaller and smaller.
The next scene is Aslan's
Camp where she comes in professed as the Queen of Narnia,
in all her glory, carried by her four cyclops. And her dress
shoots out again and she's in platinum. It's like her coronating
herself again. From there we move to the execution, or the
Stone Table, where she is in midnight blue, with a black rooster
on her shoulder, which is a bit ritualistic, which is what
the whole scene is about."
"And then she becomes a warrior, and
goes into battle. Very tawny, and Byzantine, brutal, and there's
no hint of snow, or femininity, or softness. That Maire Antoinette
beauty is gone."
