From Netflix:

As a medical engineer on her first shuttle mission embarks on a space walk with a seasoned astronaut, debris strikes their craft and destroys it — leaving the two floating through space tethered together, with no connection to Earth.

After watching Sandra Bullock spin weightlessly in space while I was clutching my seat with white knuckles and cringing, I have definitely decided that I do NOT want to be an astronaut.

As Wikipedia explains, it took three years to make this film. There are even films about the making of “Gravity”.

For the most part this is a visual adventure best seen with a large screen. Equally important are Bullock’s emotions: panic, steely determination, despair, and some elation. Early on we learn that she has cut herself off from feelings when her little girl was killed in an auto accident.

George Clooney plays a role that is secondary to that of Sandra Bullock. Rather than any special acting ability, it is putting ourselves in her place that makes the film so harrowing.

Possibly not for everyone, but definitely a cinematic achievement.
