Pre–production is the stage of the filmmaking process that occurs before filming begins. It involves the development of all the creative and logistical elements needed to create a film. This includes writing the script, designing and building sets, finding locations, casting actors, creating props and costumes, and more. Pre–production is a critical phase of filmmaking as it ensures that all the necessary elements are in place before cameras start rolling. The more organized and thorough the pre–production process is, the smoother the filming process will be.
