The film industry or motion picture industry comprises the technological and commercial institutions of filmmaking, i.e., film production companies, film studios, cinematography, animation, film production, screenwriting, pre-production, post production, film festivals, distribution, and actors. Though the expense involved in making films almost immediately led film production to concentrate under the auspices of standing production companies, advances in affordable filmmaking equipment, as well as an expansion of opportunities to acquire investment capital from outside the film industry itself, have allowed independent film production to evolve.
