Filmmaking (or, in an academic context, film production) is the process of making a film, generally in the sense of films intended for extensive theatrical exhibition. Filmmaking involves a number of discrete stages including an initial story, idea, or commission, through screenwriting, casting, shooting, sound recording and pre-production, editing, and screening the finished product before an audience that may result in a film release and exhibition. Filmmaking takes place in many places around the world in a range of economic, social, and political contexts, and using a variety of technologies and cinematic techniques. Typically, it involves many people and can take from a few months to several years to complete.
In this stage, the project producer selects a story, which may come from a book, play, another film, true story, video game, comic book, graphic novel, or an original idea, etc. After identifying a theme or underlying message, the producer works with writers to prepare a synopsis. Next, they produce a step outline, which breaks the story down into one-paragraph scenes that concentrate on dramatic structure. Then, they prepare a treatment, a 25-to-30-page description of the story, its mood, and characters. This usually has little dialogue and stage direction but often contains drawings that help visualize key points. Another way is to produce a scriptment once a synopsis is produced.
