“Dramatically, the moment in 'Gravity' that was hardest to nail down is when Ryan…” — Alfonso Cuaron

Once I finish a film, I don't ever see it again. Never ever. I have never seen any of my films since I finished them.

A lot of the films I like are more than fantasies - they're movies fascinated by the technology of space exploration, and they try to honor the laws of physics. I watched the Gregory Peck movie 'Marooned' over and over when I was a kid.

I was 8 when we landed on the moon. I was so into the space program as a kid. Eventually, I realized it was very unlikely that a Mexican kid in the early '70s was going to be an astronaut.

If you want to keep on being relevant as a director, I think you have to embrace the times. And with the times come technologies and formats.
