Film distribution is the process of making a movie available for viewing by an audience. This is normally the task that the film distributor takes on, who would determine the marketing strategy for the film, the media by which a film is to be exhibited or made available for viewing and who may set the release date and other matters. The film may be exhibited directly to the public either through a movie theatre or television and personal home viewing.
There is an example of a successful film production company called: 20th Century Fox.
A Production company is responsible for both funding and providing for a film. Therefore they need to create a tone for their productions.
