- "Extra" list: Films (extra)
A film is a work of cinematographic art, which narrates in an audiovisual way, a story or a fact. The way in which this image is projected is through a sequence of images, which at first was projected without sound, in what today is known as mute cinema, but that years later gave way to the sound cinema, which meant A contribution of paramount importance for the film industry. Usually a film is based on a script, in which the characters can or not be interpreted by actors. There is no distinction between the sensitive material in which the images are printed and the medium in which they are reproduced, such as a movie theater, television or computer. Sometimes it can be fictional as it is the majority of your case.
From a technical point of view, a film is a succession of photographic images taken with a camera, and reproduced by a film projector, using an image replacement rate of more than 18 frames per second (traditionally at 24, or sometimes at 25, even 30 or more like the 48 of the Hobbit) in such a way that creates in the human eye the illusion of continuity, without interruption between each frame due to retinal persistence.
