As someone who has worked in the book publishing business (both as a writer and as a publisher) for many years, I can second this, and offer some advice to anyone thinking of going into the book-writing or script-writing business. (The book business and the movie-script business are very similar--indeed many scripts are just adaptations from books). Years ago, when I first got started, it was do-able for a beginner to write a book or movie script and then submit it themselves to publishers and producers (these unsolicited manuscripts were referred to as "over the transom"). But today, that is nearly impossible. To be blunt, nearly all the over-the-transom submissions that companies get are worthless junk and go straight to the trash, and companies have decided that it's not worth the expense of paying a legion of readers to wade through all that junk (called "the slush pile") to find the few gold nuggets within. So today most publishers and production companies no longer accept unsolicited manuscripts or scripts, and will ONLY accept and look at projects that are submitted to them by recognized literary or script agents. So if you want any chance of actually getting a book published or a script produced, you MUST find a literary agent to represent you. You can find literary and script agents listed in "Writers Digest" or "Writers Market" (most libraries have current editions of those), and there are probably compilations of literary agents on the Net too.As far as contacting the powers that be at fox, well, I've been trying (on my own) for months to get ahold of someone, or at least get a response. I’m sure you know that Hollywood, at the end of the day, is looking to make money, so you may end up having to use a ‘middle- man service’ (these too are part of Hollywood) to pitch your idea to 20th Century Fox. I’ve decided to use one of these “middle-man services” myself via what's called a 'copyright clearance service'. I’m not sure what type of service you’ll need in order to successfully submit your idea. FOX producers see thousands of move idea scripts per year, and a great deal of them get rejected.
If possible, I would contact the Thomas Brothers, to see how they went about submitting their idea
( screenplay) to FOX. ‘Predator’ was their very FIRST screen play, and they hit a home run with it!
