What happens in pre-production film?

Pre-production refers to the tasks that are undertaken before the production begins. What is included in this stage of pre-production depends on the medium and situation., e.g, for a small video company, pre-production may be referred to everything that happens before the shooting begins such as; meeting with clients, research, planning and scene setting. However, for film producing, pre-production is more specific. Pre-production for film producing could include; location, prop and wardrobe preparation, special effects, production scheme, set construction, a finalised script and a script read through with cast, directors and other parties.
