Selling a screenplay is like drawing a map on water. As soon as you draw it, it's gone. No one can follow that path. The person who drew it can't even follow it. Timing and luck are just as important as talent. And persistence. I can't emphasize that enough. You have to be persistent. Here is what I suggest. It worked for me. It might work for you.
1. Subscribe to IMDbPro. You can't contact people if you don't know how to reach them. IMDb doesn't have email addresses for everyone, but it does have email addresses for a lot of people. With some good detective work you can figure out some people's addresses based on the general address for their company.
2. Find producers who have produced the kind of movies you write and send them a query letter via email.
3. Don't send queries on Monday or Friday. People in the movie business hardly work as it is, so don't let your query get buried with all the other junk that comes in over the standard Hollywood "four-day weekend."
4. Don't put the word "query" in the subject line. In fact, don't use the word "query" at all. Just put the title of your script in the subject line. Even with people who delete all queries without even opening them, you still might have a chance if they think it's a film they're supposed to know something about.
5. The very first line in the body of your email should be the logline for your script. A one-sentence, standalone paragraph consisting of the logline. Nothing else. Thirty-five words or less. Not 36, 56, not 76. Thirty-five words or less. If you can't do that, you have not thought about your story enough. Pare it down to its very essence.
6. The only exception to Rule 5 (the logline being the very first line) is if you have produced credits. And by that I mean real produced credits, not home movies. If you do, then start off with something like this: "I wrote the Lionsgate movie XXX XXX..."
7. The next line should be, "My new script is a xxx-page thriller (or romance, comedy, etc.) titled XXXXXXX. I suggest mentioning the page count and genre because it lets the person know you are a professional if your page count is between 90 and 120. Personally, I think 100-110 is the perfect length. Mentioning the genre lets the person know what to expect.
8. A good next line is, "Comparable films include big hit, big hit, and big hit."
9. Send queries to every producer you can find. Sometimes I use one of those query blast services that charge $50 or $60 and send your query out to three or four thousand producers. Twice I got $10,000 options on queries sent out that way. Make sure to tell the service NOT to put the word "query" in the subject line.
10. Create a list of producers who respond because even if they don't buy your script-and the odds are they won't-you are at least starting to build your network. Now you have someone to send your next script to and it's based on a personal connection. So your next query to that person would start off with something like this: "Jim, last year you read one of my scripts and had some good things to say about it. I just finished a new script called XXXX, about a..."
11. ABQ - Always Be Querying. Research producers, identify those who make movies like you write, and send them fresh queries. Which means you need fresh scripts. Don't be one of those writers who spends 10 years trying to sell his "masterpiece." You should always have a new script in the works. Always.
12. Don't get too excited when a producer asks for your script. That is not a sign that you are 75% of the way to a sale, or 50%, or even 25%. A producer asking to read a script is an important first step in the process, but it's one step out of about a hundred. Half the people who ask for a script won't read it. Of those who do read it, probably half again won't bother to respond. And almost all of the rest will give you a canned response along with a pass. If you're lucky, one out of a hundred producers who read your script will like it enough to try to make a movie out of it.
13. Oh, and one more thing. Don't waste your time querying studios, big production companies, or LA-based agents. They will not deal with you. Trust me.
