I am writing because my father has recently written a book that I think would make a terrific movie. I would like to help my dad, however I am not sure what the proper procedures are in getting a book made into a movie. Any help would be greatly appreciated.
While you didn’t say this in your question, I do want to point out that I know somewhere along the way we’ve discussed that books and movies are two separate worlds and writing a book that would make a great movie does not necessarily mean it will make a great book, just as great books don’t necessarily translate into movies (let alone great movies).
However, if you are unpublished and want to hit two markets at once, both the book and the film market, then what you’re going to have to do is write the script and submit that, separately from the book, to film agents and production companies. I’m sure there are people who read this blog who can give much better advice than I can on this subject, so I’ll avoid saying anything further.
When a book is published and picked up by a film company the company typically hires a scriptwriter to make your book into a film. When you are unpublished that’s typically your job. Either you need to pay a scriptwriter to turn the novel into a script or you need to learn scriptwriting and do it yourself.
