Some digital movie projectors don't even require a harddisk they receive the data via satelite. Distribution on film is expensive and I understand the producers what I don't understand are festivals that stopped accepting film copies and only accept digital copies. Festivals sell themselves as the place where indepent and quality cinema is shown but they don't accept a quality product anymore. At least movies even digital ones are getting archived on film stock not all (lack of budget) but some. In Europe it's not only the producers that forced the change but also the individual countries.
