“When you're doing a film, narrative is your most important tool, but it's a tool…” — Alfonso Cuaron

Dramatically, the moment in 'Gravity' that was hardest to nail down is when Ryan is in the Soyuz capsule and she realizes that she's out of fuel. That's when the character's arc gets defined.

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.
