Here is a post on methods for making films, with a specific focus on the value of pre-production.

When we think of some of the greatest films of all time, unbelievable acting performances enter your mind. Indeed, the characters of the most popular movies of all time have actually entered into folklore throughout society. How do actors go about putting in unbelievable performances then? Well, naturally it depends upon the technique of each actor. For instance, some actors are renowned for their 'method' approach, whilst others opt for a more naturalistic approach.

What is pre-production in film? Why has it been very important in the making of the greatest films of all time? Essentially, pre-production is the preparation stage of filmmaking. It is where the script is developed and settled. In some cases a script might be solely developed by one author; other times it might be collaborative in its making, whether that be through a team of authors or in partnership with the director. In any case, the script serves as the blueprint for the subsequent filmmaking, informing its visual, direction and casting. Certainly, each line in a script needs to be refined so that it is ready to be presented to producers, actors and other partners; essentially, the director has to understand the script inside out. Each sentence has to make sense on an imaginative level; the script basically needs to be cohesive and finely tuned. Another essential aspect of pre-production is location hunting. This part of the filmmaking process is performed by the director and lead cinematographer; other key collaborators, such as the script author, executive producer and lead actors might also offer input and assist during this stage of pre-production. Location searching is important, since it means that when filming is ready to begin, you already understand what you are looking to catch on celluloid. On a practical level, location searching is likewise helpful for preparing recording licenses, comprehending daylight concerns, noise and background aspects, as well as scheduling times and dates for the shooting itself. Basically, all these aspects of planning need to be carried out before even anything is shot. The founder of the activist investor of Sky would acknowledge the importance of pre-production in films, for example> as would the CEO of a major shareholder of Netflix.

Postproduction plays an essential part in the making of the most popular movies in the world. Why is this the case? Well, we can think of postproduction as the final stage of making a motion picture. It is where a collection of filmed video footage is modified and turned into a cohesive series of scenes. Lighting, filters, camera angles and special effects are just a few examples of postproduction components that can be worked on during this phase of filmmaking. The CEO of the company that owns Hulu would acknowledge the significance of postproduction in filmmaking, for example.
