“On day one, we were in Lucasfilm in San Francisco with Industrial Light and Magic and John Knoll, our supervisor, he said that they’ve got a brand new 4K restoration print of A New Hope – it had literally just been finished. He suggested we sit and watch it. Obviously, I was up for that. Me, the writer, lots of the story people and John all sat down, we all had our little notepads, we were all ready for this. I’ll add that I’ve seen A New Hope hundreds of times. So I was sat there, ready to take notes and really delve under the surface of the film. You have the Fox fanfare, then scrolling text with ‘A long time ago…’, and then the main music begins. Next thing we knew it had ended, and we looked around to one another and just thought – shit, we didn’t take any notes. You can’t watch it without getting carried away. It’s really hard to get into an analytical filmmaker headspace with this film. It just turns you into a child.”"
