Billing is a film term denoting the amount and order in which film credits information is presented in advertising and on the film itself. Information given in billing usually consists of the actors appearing in the movie, the directors, producers, the companies producing and distributing the movie (by name and/or logo), and artistic and technical crew. The title of the movie is also considered to be part of the billing.
In the layout of film posters and other advertising copy, the billing is usually placed at the bottom of the poster in what is known as the billing block.
