The film is not only a cultural product or industry, but a mixture of these two concepts, is a “sui generis” product, the outcome of creation and artistic-industrial construction. In the film industry, what usually sells is an idea, a concept. Each film is a unique creation, containing a mix of elements, combined in some way. It can therefore be considered as a prototype. When people buy a product that is new they first try, which is not just like in this industry, the film can be defined as a product that is sold only once.
