"Gravity," opening today, is the story of two astronauts struggling to stay alive after they become untethered from their spacecraft.
The idea for the film started with Cuaron's son,
"But I always feel the right person ends up making the film," she said seriously.

The director understood, but he had his own problems.
After consulting with astronauts, he "realized we were morons" when it came to gravity. What they hadn't taken into account was recoil. In space, if you throw a ball, that ball will go until something gets in its way to stop it.
