I like the idea of the documentary as a portrait. There's not a chronological beginning, middle, and end structure. You build something in the editing room that's shaped by getting to know the person and digging deeper, unpeeling the layers of them as you get to know them.
There are not the same factual shows anymore - children's TV has become much more trivial.
I empathize with women in their high heels so I'll be there in my kilt and T-shirt and I'll walk around all day just to prove that if I can wear the shoes for 36 hours then certainly our customer can wear them.
