Pre-production involves planning all logistical elements of a film before shooting begins. This includes breaking down the script, creating a budget and schedule, assembling a crew, planning each department's needs, casting actors, and holding rehearsals. Key parts of pre-production are costume and production design, which involve finding appropriate costumes, ensuring all visual elements have a consistent style, and conducting costume fittings. Successfully completing pre-production lays the groundwork for a smooth production process.
