The making of a film can often be as interesting as the film itself, if not more. In some cases both the final cut of the movie and the documentary of the creative and tech production processes are so tightly meshed as to become almost inseparable,
One example of this is Stankley Kubrick’s 2001 Space Odyssey, a cinematic wonder of a story that mesmerizes audiences to this day. Let alone that back in the day one could smoke in cinemas, which helped highly visual narratives find wide4r and wider niche audiences. Let alone that the script was only 67 pages last time I saw it, and forget the complete control the director held over the entire studio process, in England, not Hollywood.
