Musician/Novelist/Screenwriter Nick Cave is interviewed by Suicide Girls on the promo of his new film "The Proposition." 

I think that once you've written a couple of film scripts you can never write a novel again. Also I just never had any desire to write another one. It's just not something that I've wanted to do. Writing one in the first place was just this perverse idea at the time. Someone said I should write a novel and I went, “Oh, okay.” It was that type of thing and I wrote one and I don't have any ambitions to be an author really. For me I just really want to be a songwriter. That's what I'm primarily interested in.
