Movie Making

Today I watched a movie. I mean, i watched it again today. I had watched it yesterday. But when I was watching it today, I looked at it with a different angle; angle of direction. I carefully payed attention to focus and closeness and frame of camera, number of changes in the camera, background music, etc. This only tells that direction is an art. I think, a director must first make movie in his mind and then he should be shooting it. He must be clear in his mind about how his movie is gonna look like. From what I saw, I think when they shoot a scene, they use number of cameras, simultaneously and when they edit the movie, they use best shots from these cameras. These cameras are time synchronized. By the way, the name of the movie was 'The Uninvited". It's worth a watch.
