I don't think that there is any hard and fast rule that says that documentary has to be linear at all.

We don't see many films in which someone with schizophrenia is the main character.

One thing people often forget when making a documentary is that, in a sense, you still have to cast, find a star, and it has all of those built-in challenges.

It can be difficult to present mental illness in film without resorting to devices that, if not handled well, can seem heavy-handed or cliché.

I think that every film should have its own structure, and that's the beauty of film language - is that we get to express that deeply individualistic side of ourselves.

We all use dishwashers every day and yet none of us would say that we're experts on dishwashers, but somehow we all think we're experts on movies.

In documentary you sometimes see the tyranny of the linear, but what I've noticed in the last ten years in narrative film is the tyranny of the non-linear.
