Diamond Jim asks about NEVERWHERE
Neil relates that he started the novel during breaks in the [BBC] series when he saw how far it was straying from what he intended. That seems like a really unusual situation--a writer getting to novelize his own script--and if you have any reflections it would be very interesting to hear them.
It is rare. I have the novelization rights in some of my projects; I don't have it in others. I guess he retained his, as a Famous Comics Writer.
If you haven't retained the print rights, you could ask the network to let you write the novel and try to work out a deal. Usually in US TV the writers are way too busy, and are paid too much to be able to afford to write novels. The UK system has shorter series, which leaves more time for a writer to write a novel. And, I guess, the English read more.
