Lubezki says some days went like this: “Eight a.m., the camera doesn’t work. Ten a.m., the shot doesn’t exist. Eleven a.m., might not shoot anything today. It was really scary shit.” Lubezki started a diary “so that when we’re fired, I want to be able to go back and see what happened.” Recently he reread part of it. “For fifteen days it is really rough,” he says. “Like Shackleton.”
And when the shooting was finally over, there was a year and a half of postproduction work left. “Was I worried?” Cuarón says. “Yeah!” He and Lubezki would watch their footage, “and depending on the day, you’re just in a room laughing, like, What the heck are we doing? Chivo’s favorite phrase was, ‘This is a disaster.’ Some days you’d just have bits and pieces of Sandra Bullock in a box, floating around, surrounded by robots with cameras and lights on them, and you’d think, This is going to be a disaster."
So basically, every theory we had about how they did it was a little right and a lot wrong.
4-days later, I can appreciate the length of this article. True craftsmen want to get things right, no matter the miscalculations of time.
