I would like to write a screenplay but am wondering technically how to write it. Thank you in advance for any responses, and please do respond.
Screenplays have their own format.
But the best thing to do is to read a whole bunch of scripts. Read as many scripts as you can before you start writing one. Bill Martell is right on the money. I have downloaded the scripts from the sights suggested by him and have bought several others in the subject area I want to write of. I, like you, couldn't think of how to begin this process without any formal education in the subject area of screenwriting and figured this is one way of attacking my problem.
