This document discusses how films are produced and distributed through case studies of three production companies: Working Title Films, Warp Films, and Twentieth Century Fox. It explains that Working Title Films, as part of a major studio, has financial backing that allows it to greenlight films based on their marketability and profit potential. Independent Warp Films has stricter financial constraints and relies on public funding. While major studios have advantages in equipment and resources, digital technology has helped independent films compete on similar levels through lower production costs.
