If you are writing a script or planning to write a script, it is a very good idea to get some advice first from experts. I have chosen three short videos to help you. I like them because they are clear and easy to understand but feel free to do your own research. As one expert reveals, there are thousands of books and videos on how to write a great screenplay. If they all worked then everybody would be writing award winning screenplays. They're not. Success comes from learning from a wide range of sources and then coming to your own conclusions and developing your own style.
