Screenwriting is the art and craft of writing scripts for mass media such as feature films, television productions or video games. It is frequently a freelance profession.

Screenwriters are responsible for researching the story, developing the narrative, writing the screenplay, 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. They either pitch original ideas to Producers in the hope that they will be optioned or sold, or screenwriters 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.

There are many script writing professionals from ancient days, their main work is to write a fine script.

The act of screenwriting takes many forms across the entertainment industry. Often, multiple writers work on the same script at different stages of development with different tasks. Over the course of a successful career, a screenwriter might be hired to write in a wide variety of roles.
