It’s only been a little over 10 years since Alfonso Cuarón’s space-disaster survival adventure Gravity made a huge, Oscar-winning splash with a story that takes place almost entirely in a zero-gravity setting, leaving Sandra Bullock and George Clooney bobbing around like balloons throughout most of the action. At the time, the visuals seemed shocking and attention-grabbing, enough to spark an extensive wave of “How did they do that?” technical pieces focusing solely on the zero-gravity effects.
