Explanation

A film, also known as a "movie" or a "motion picture," is a series of moving images shown on a screen, usually with sound, that make up a story. Some people like to see new films at the theater as soon as they're released. You might pretend to be a fan of French films while secretly preferring animated films. The movie itself is a film, and you can also use the word to mean the photographic strip of plastic that runs through a camera and captures the film's images. It's also a verb, meaning to use such a camera: "Let's film a scene where you play with my cat!" The Old English root word is filmen, "membrane or thin skin."
