It’s a film of such jaw-dropping virtuosity, such sublime cinematic pleasure, such thrilling technical genius—we simply had to make “Gravity” this year’s opener at our outdoor cinema under the stars. Two astronauts—one a veteran (George Clooney) on his last mission, one a newbie (Sandra Bullock) on her first—confront unimaginable challenges after disaster strikes during a routine spacewalk. Facing deafening silence, indescribable solitude, and total desolation over 400 miles away from Earth, the tension builds to near heart-stopping levels as the human will to survive takes flight. Both a massively entertaining space adventure and a visionary work of transformative art, Alfonso Cuarón’s out-of-this-world masterpiece is the kind of dazzling artistry that only comes along once in a blue moon.
