We are suffocated by writers who want to enlighten us with their truths. For me, the theatre is beautiful because it is a secret, and secrets seduce us, we all want to share secrets.
I am so far as I am aware not at all influenced by dramatists, expect for Shakespeare, who I have to say, it is impossible not to be influenced by if you hold language to be the major element of theatre.
I've often taken important classical, biblical or literary stories and interrogated them. I have tried to reinvigorate Lot by interpreting it differently.
When I write, I am not giving a lecture, I am speculating on behavior. Sometimes this is dangerous, but it should be. As I say often, theatre is a dark place and we should keep the light out of it.
