For some years, I've been very interested in the relationship between science and art.

Haunted since the day its discovery was projected all over the world in 1994, I, like many others, have always wanted to see inside the Chauvet cave, site of the world's earliest known cave art. Quite rightly, we will never go. It is closed to the public.

So you might say, 'Why do you end up making theatre in a world in which there is already too much of that? Creating layer upon layer of artifice?' Perhaps the function is to pierce through that cloud and show reality - so the function of art is to make things - to show: 'Hang on, this is real.'

Theatre is the art form of the present: it exists only in the present, and then it's gone.
