Re: Novels based on the movie cast.
How is it insulting? I'm just a freelance contractor. I knew going in that what I created was the property of CBS and Pocket, and once I turned it in, it was theirs to do whatever they chose with, including not publishing it. They're under no obligation to explain their decisions to me. Pocket's only obligation was to pay me for my work as specified in the contract, and they met that obligation in full. And they've kept hiring me to do more work, and that's where a writer's focus needs to be: on the next work.
I do know a couple of minor things that I was told in confidence, but not enough to tell me why the situation is the way it is. At best, I have speculations that are slightly more informed than most.
Well it's good that you have no hard feelings about it.
Glory be to the Father, and to the Son, and to the Holy Spirit.
