Scenes describe which events happen over time. Together with actors events comprise the story. Visually scenes are divided into shots . Shots are different camera views of the same scene. Shots are usually divided into close-up, medium shot, and long or establishing shots.
Shots are the smallest visual units.
Almost all movies are told from a third person point of view . That is, the viewer of the movie is not involved in the story, but an observer. Using this way of story-telling it is easy to create tension, humor, anticipation etc., as usually the viewer is provided more information than the main characters of the story. On the other hand, information can be withhold for the same dramatic purposes. Thus a scene at the beginning usually happens earlier in time than a scene in the middle or at the end of the movie.
