Screenwriting, also called scriptwriting, is the art and craft of writing scripts for mass media such as feature films, television productions or video games. It is often a freelance profession.
Screenwriters are responsible for researching the story, developing the narrative, writing the script, screenplay, dialogues and delivering it, in the required format, to development executives. Screenwriters therefore have great influence over the creative direction and emotional impact of the screenplay and, arguably, of the finished film. Screenwriters either pitch original ideas to producers, in the hope that they will be optioned or sold; or are commissioned by a producer to create a screenplay from a concept, true story, existing screen work or literary work, such as a novel, poem, play, comic book, or short story.
