Pre-production refers to the tasks that must be completed before filming begins, such as hiring actors and models, building sets, budgeting, planning, scheduling, renting equipment, and conducting tests. Key pre-production tasks include finalizing the production schedule, casting actors, coordinating special effects, wardrobe, special equipment, stunts, extras, props, makeup, hair, atmosphere, vehicles, animals, sound effects, music, and notes. Producers typically select the creative team, assist with financing, and approve locations, schedules, scripts, and budgets in pre-production.
