The term 'Movie Film' can be summarized as a type of film that is used to create motion pictures. It is also known as a REEL, which is a four-letter word. Movie film is a strip of transparent plastic film base coated on one side with an emulsion containing light-sensitive silver halide crystals. When the film is exposed to light, it captures images that can be developed into a motion picture. Movie film is used in both digital and analog formats, and is the medium of choice for many filmmakers.
