The production process of films involves four main stages: idea development, pre-production planning, production, and post-production. In the idea development stage, the producer, writer, and location scout work to develop the ideas for the film. During pre-production planning, the producer, writer, script writers, accountants, and location scouts plan the plot, budget, and schedule. In the production stage, the camera operator records the actors performing scenes under the direction of the director while the sound engineer and stunt crew also contribute. Finally, in post-production, the editor adds sound, graphics, and does the final edit under the director's supervision.
