Was the wig a kind of transformational moment?

I felt that GJ is one of those people who you get a lot of information about her immediately, visually and also line-wise. When Peter Mullan's character, early on in the first episode, says, "What is it? He, she, it?" I felt there was a certain fulfillment that I wanted to have visually with this character, so that she could inhabit "he, she, it." And the wig was, like you said, good transportation. Did you say transformation or transportation?

Either way it works, right?

Both.

At one point, GJ's past is described as a "calamity." Do you have any insight into that?

Well, you know, that's a mystery, the calamity. And it remains a mystery. But it's a physiological — not really a metaphysical. It was more of a cellular change that the character speaks of. But that really is not covered. It remains an inexplicable passage.

I wonder if Campion could come back to the character and give her her own miniseries.

Well, if Jane does "Top of the Lake: Part Two," maybe we'll find out more about what that was.
