Each story we approach in the same way, with curiosity and interest and determination to get behind the image.

Press coverage has been difficult for him. I did not set out to ensnare him with a child.

The children don't wear their masks at home and in controlled surroundings.

We wanted to make sure that the film covered the main issues of his life. Musicianship, appearance.

A teenage taste of beer aside, Mitt Romney does not consume alcohol. Which begs the question, will total abstention put his candidacy, perhaps even this great nation in jeopardy?

This was almost two hours of factual documentary. In our audience ratings, barely no one left the programme. The whole of his life is so fascinating and people kept watching for that reason.
