That big budget blockbuster at the cinema right now. Before they started filming anything they made a storyboard.
The whole film, drawn in little boxes like a giant comic graphic novel. It helps the team figure out the camera angles, lenses, editing sequences etc. When it comes to the shoot they are simply replacing the sketched scene with the actual one. Sort of. To put it super simply.
When I was a teenager I worked in a cinema. Not selling popcorn, but up in the projection booth, prepping the big 35mm rolls of film for the main screening on Saturday. Every Friday night I would wind through these big reels of film to get them ready. I began to understand that a film is just a series of photographs played sequentially one after the other. Frame by frame, scene by scene. A film is a linear thing, you have to watch it in order, and most of the time the order goes beginning, middle, end.
