A film poster is a poster used to advertise a film. There may be several versions for one film, with variations in regards to size, content and country of production of the poster. It usually contains an image with text, though this has evolved over time from image-free bill posters through to the highly visual digital productions of today. The text usually contains the film title in large lettering and often the names of the main actors. It may also include a tag line, the name of the director, names of characters, the release date, etc.
