Some philosophers would claim that the true key to fear is to have us face a very real, existential fear that is all buried within us. "Gravity," a groundbreaking 3D astronaut drama, does just that: two astronauts stranded in outer space, with nothing to hold on to, literally staring the world in the face, in between plummeting into a fiery death or death by vanishing into the unknown. Ultimate existential fears, indeed. 

"Gravity" revolves around veteran astronaut Matt Kowalski (George Clooney) and Medical Engineer Dr. Ryan Stone (Sandra Bullock) who has come into space for the first time and is rather nervous about it. They are both tasked to fix the Hubble Space Telescope.

They are about to be heading back to Earth when Houston raises an alarm, instructing them to seek shelter in the shuttle--a missile had destroyed a sattelite and debris from the collision has scattered and is rushing towards their direction at a deadly speed. But the shuttle is hit, and Stone is thrown off into space, her tether disconnected, and floating dangerously away from anything to hold on to. 

Kowalski rescues her, but that is not the end of it. They are cut off from all communication on Earth and their oxygen is running low. Their only hope for salvation is to head further into the dark void toward a Russian Space Station. 

Despite the chilling premise however, an actual astronaut who in real life had gone on missions to the Hubble Space Telescope, points out the many glaring plot holes in the 3D film: The events would have been completely impossible.

The Hubble and the space station are, unfortunately, in different orbits: the telescope is located near the equator, while the space station is a hundred miles below it, and located further north, over Russia. 

The distance that Kowalski and Stone would have to cover, in reality, would be comparable to "having a pirate tossed overboard in the Caribbean to swim to London." 

But that would not deter moviegoers; It is Alfonso Cuaron's first return to the big screen for years, and the film was done completely in green screen, and is a stunning visual piece. The thrilling, fast-paced narrative is also a plus.
