I was trained as a neurologist, and then I went into the theater, and if you`re brought up to think of yourself as a biological scientist of some sort, pretty well everything else seems frivolous by comparison.
I spend a lot of my time trying to draw the attention of actors to the minute and subtle details of human behavior, which was the sort of thing I was looking at when I was a neurologist.
I became startled by the extraordinary difference between something whose surface is completely invisible which only makes itself present by virtue of what it reflects, and a window, which doesn`t make itself apparent at all, in the ideal case.
