Filmmaking is the process of making a film. The nature of the film, and the budget, determine the size and type of crew used during filmmaking. Many Kollywood films employ a cast and crew of thousands and have non-complicated computer generated imagery (CGI), while a low-budget, independent film may be made with a skeleton crew, often paid very little. Filmmaking takes place all over the world using different technologies and techniques, and is produced in a variety of economic contexts that range from state-sponsored documentary.

Screenwriting refers to the art and craft of writing screenplays Writing for film is potentially one of the most high-profile and best-paying careers available to a writer, and as such, it is perhaps the most sought. Writing a screenplay requires the creativity of a storyteller and the skills of both the dramatist and the filmmaker. Because of the particular combination of skills and standards required by the motion picture industry, many writers find screenwriting more challenging than writing novels or other narrative fiction.
