A film, also called a movie or motion picture, is a story conveyed with moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry. 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 give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer. 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) has historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, moving picture, photo-play and flick. A common name for film in the United States is movie, while in Europe the term film is preferred. Additional terms for the field in general include the big screen, the silver screen, the cinema and the movies.

A clip from the Charlie Chaplin silent film The Bond (1918) Preceding film by thousands of years, plays and dances had elements common to film: scripts, sets, costumes, production, direction, actors, audiences, storyboards, and scores. Much terminology later used in film theory and criticism applied, such as mise en scene (roughly, the entire visual picture at any one time). Moving visual and aural images were not recorded for replaying as in film. Anthemius of Tralles used an early type of camera obscura in the 6th century The camera obscura was further described by Alhazen in his Book of Optics (1021), and later near the year 1600, it was perfected by Giambattista della Porta. Light is inverted through a small hole or lens from outside, and projected onto a surface or screen, creating a moving image, but it is not preserved in a recording. In the 1860s, mechanisms for producing two-dimensional drawings in motion were demonstrated with devices such as the zoetrope, mutoscope and praxinoscope. These machines were outgrowths of simple optical devices (such as magic lanterns) and would display sequences of still pictures at sufficient speed for the images on the pictures to appear to be moving, a phenomenon called persistence of vision. Naturally the images needed to be carefully designed to achieve the desired effect, and the underlying principle became the basis for the development of film animation. With the development of celluloid film for still photography, it became possible to directly capture objects in motion in real time. An 1878 experiment by English photographer Eadweard Muybridge in the United States using 24 cameras produced a series of stereoscopic images of a galloping horse, is arguably the first "motion picture," though it was not called by this name. This technology required a person to look into a viewing machine to see the pictures which were separate paper prints attached to a drum turned by a handcrank. The pictures were shown at a variable speed of about 5 to 10 pictures per second, depending on how rapidly the crank was turned. Commercial versions of these machines were coin operated. 
A frame from Roundhay Garden Scene, the world’s earliest film produced using a motion picture camera, by Louis Le Prince, 1888 By the 1880s the development of the motion picture camera allowed the individual component images to be captured and stored on a single reel, and led quickly to the development of a motion picture projector to shine light through the processed and printed film and magnify these "moving picture shows" onto a screen for an entire audience. These reels, so exhibited, came to be known as "motion pictures". Early motion pictures were static shots that showed an event or action with no editing or other cinematic techniques. Ignoring Dickson’s early sound experiments (1894), commercial motion pictures were purely visual art through the late 19th century, but these innovative silent films had gained a hold on the public imagination. Around the turn of the 20th century, films began developing a narrative structure by stringing scenes together to tell narratives. The scenes were later broken up into multiple shots of varying sizes and angles. Other techniques such as camera movement were realized as effective ways to portray a story on film. Rather than leave the audience with noise of early cinema projectors, theater owners would hire a pianist or organist or a full orchestra to play music that would cover noises of projector. Eventually, musicians would start to fit the mood of the film at any given moment. By the early 1920s, most films came with a prepared list of sheet music for this purpose, with complete film scores being composed for major productions.

The rise of European cinema was interrupted by the outbreak of World War I when the film industry in United States flourished with the rise of Hollywood, typified most prominently by the great innovative work of D.W. Griffith in The Birth of a Nation (1914) and Intolerance (1916). However in the 1920s, European filmmakers such as Sergei Eisenstein, F. W. Murnau, and Fritz Lang, in many ways inspired by the meteoric war-time progress of film through Griffith, along with the contributions of Charles Chaplin, Buster Keaton and others, quickly caught up with American film-making and continued to further advance the medium. In the 1920s, new technology allowed filmmakers to attach to each film a soundtrack of speech, music and sound effects synchronized with the action on the screen. These sound films were initially distinguished by calling them "talking pictures", or talkies. The next major step in the development of cinema was the introduction of so-called "natural" color. While the addition of sound quickly eclipsed silent film and theater musicians, color was adopted more gradually as methods evolved making it more practical and cost effective to produce "natural color" films. The public was relatively indifferent to color photography as opposed to black-and-white, but as color processes improved and became as affordable as black-and-white film, more and more movies were filmed in color after the end of World War II, as the industry in America came to view color as essential to attracting audiences in its competition with television, which remained a black-and-white medium until the mid-1960s. By the end of the 1960s, color had become the norm for film makers. Since the decline of the studio system in the 1960s, the succeeding decades saw changes in the production and style of film. Various New Wave movements (including the French New Wave, Indian New Wave, Japanese New Wave and New Hollywood) and the rise of film school educated independent filmmakers were all part of the changes the medium experienced in the latter half of the 20th century. Digital technology has been the driving force in change throughout the 1990s and into the 2000s.
