Protect your idea by writing it as a treatment or a script and submitting it to the Writers Guild of America. A $20 fee will register it with the Guild for five years. This shows that the idea is yours and that you created it on the date that you registered it. It doesn't mean other people didn't have a similar idea on the same day, but it protects you from other people stealing it and calling it their own. It is a good idea to give the treatment or script to a lawyer or agent and see if they want to represent it.This
offers additional protection and may help you get more meetings.
With so many movie ideas are out there, your idea needs to stand out from the rest. Your idea shouldn't be complicated, yet it should be an original take on a familiar theme. There are numerous movie ideas about monsters, but what is it that makes your monster movie idea special? You should be able to explain your idea in one or two simple sentences, i.e., a love story on board the Titanic during its first and last voyage; four guys wake up in Las Vegas after a crazy bachelor's party having no idea what happened to them the night before; a sheriff who is afraid of the water must kill a shark that is preying on swimmers in his beach community.
The movie business is just that--a business--so it's important to think about why your movie idea would be something people would be interested in seeing. How is this idea important to the times in which we live? Who would be in it? Has this kind of movie been made and, if so, to what types of movies is it similar? What would the movie poster look like? Answering these questions will take some research of movies that have been made and how much money they made. Most movies are are made to make money. If you can convince people that your movie idea will make money, then it will have a much better chance of getting made.
