I am grateful to theatre for making me what I am today. But it's not like theatre is my first love. I am equally attached to cinema, which is, actually, a child of theatre, since it borrows heavily from it.
In many ways, theatre is more rewarding for a writer. I used to think it was like painting a wall - that when the play is finished, it's done - but now I realise it's more like gardening; you plant the thing, then you have to constantly tend it. You're part of a thing that's living.
