When Nolan himself recently tried to arrange a screening of Steven Soderbergh’s 2002 ‘Solaris,’ he was alarmed to learn from the studio (Fox) that they had no 35mm print or DCP[— the current industry standard for digital projection —] available. A standard-definition DVD (as no Blu-ray exists) or a high-definition digital download were the only options — adequate for home viewing, perhaps, but insufficient for projection on a large cinema screen.
