Christy Turlington

I remember doing a shoot for Herb Ritts, hanging off the Eiffel Tower - that wasn't your usual day at the office. It was terrifying, and in the end, you couldn't really tell how high I was because the photographer was scared of heights, so he was quite far away from me.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
