Film encompasses individual motion pictures, the field of film as an art form, and the motion picture industry. Films are produced by recording images from the world with cameras, or by creating images using animation techniques or special effects.
Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating — or indoctrinating — citizens. The visual elements of cinema gives motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue.
Traditional films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
The origin of the name "film" comes from the fact that photographic film (also called film stock) had historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, photo-play, flick. A common name for film in the United States is movie, while the Europeans prefer cinema. Additional terms for the field in general include the big screen, the silver screen, the cinema and the movies.

Film may be combined with performance art and still be considered or referred to as a “film”. For example, when there is a live musical accompaniment to a silent film. Another example is audience participation films, as at a midnight movies screening of The Rocky Horror Picture Show, where the audience dresses up in costume from the film and loudly does a karaoke-like reenactment along with the film. Performance art where film is incorporated as a component is usually not called film, but a film, which could stand-alone but is accompanied by a performance may still be referred to as a film.
The act of making a film can, in and of itself, be considered a work of art, on a different level from the film itself, as in the films of Werner Herzog.
Similarly, the playing of a film can be considered to fall within the realm of political protest art, as in the subtleties within the films of Tarkovsky. A "road movie" can refer to a film put together from footage from a long road trip or vacation.
