Motion picture, also called film or movie, series of still photographs on film, projected in rapid succession onto a screen by means of light. Because of the optical phenomenon known as persistence of vision, this gives the illusion of actual, smooth, and continuous movement.
The motion picture is a remarkably effective medium in conveying drama and especially in the evocation of emotion. The art of motion pictures is exceedingly complex, requiring contributions from nearly all the other arts as well as countless technical skills (for example, in sound recording, photography, and optics). Emerging at the end of the 19th century, this new art form became one of the most popular and influential media of the 20th century and beyond.
