Film is a visual medium. and It is crucial when writing a screenplay to SHOW your audience your story, as opposed to telling it. Less is more. Screenplays can be original works or adaptations from existing works such as novels. A screenplay differs from a script in that it is more specifically targeted at the visual, narrative arts, such as film and television, whereas a script can involve a blueprint of “what happens” in a comic, an advertisement, a theatrical play and other “blueprinted” creations.  Often times, and for all intensive purposes of this website, the words script and screenplay are used interchangeably.
