During the hight of film production there were huge machines that turned out film daily to supply the market with the film it used. After the demand plummeted it was impossible to scale these machines. The only way these machines could run and pay for the huge investment was to produce ridiculous amounts of film. Today those machines have been downscaled whenever possible and just run from time to time. It's just a huge investment to build them up from scratch. It's like a school bus, it makes sense when you are filling it with kids but when you are only transporting one kid back and forth from school it's doesn't make economic sense.
