I've googled and too much joy to be of use - nothing obviously linking to a text - and I've checked SciFi Scripts.
Does anyone know where I can get it?
Important research here....
Oh, and something that came up when I was talking to Neil. He was concerned that future thesis-writers will pick up on a theme that isn't actually his.
In Mirrormask, especially in early versions, Helena draws things that turn out to be true in the other world. In Wolves in the Walls, the heroine draws the wolves on the curtain before they make a sound. In the first instance, this was Dave's idea, and in the second, the director's.
I said that well, yes, there is the artistic personality known as Neil, and this seems not to be his kink, but on the other hand, there is the artistic personality known as Neil'n'Dave, and that is a different matter.
The job of future researchers will be to distinguish the one from the other.
