I have written a science fiction trilogy that is selling like crazy. The last book in the saga is with my editor now and the audio edition of the second volume was just released on Amazon, Audible and iTunes. I never expected this kind of success. I get tons of email from fans demanding the story be made into a movie. I am totally clueless where to even start considering it. I am working on my first script, based on one of my short stories, just to figure out that process. That's my first step. Any advice?
