Episode 45: Gravity

Click to Play!

Back from the ramparts of Beijing in the last episode, Sean and Cody blast off for another trip to outer space as they set a course for this epic 2013 survival drama directed by Alfonso Cuarón. In Gravity, chatty astronauts Ryan Stone (Sandra Bullock) and Matt Kowalski (George Clooney) are busy giving the Hubble Telescope a once-over when a wave of supercharged space junk turns their space shuttle into confetti. Drifting off in opposite directions and with the oxygen in their suits running out, the two have to think fast to figure out not only to survive the next 90 minutes, but how to get back on terra firma now that their spaceship is a glitter bomb. Environmental issues discussed include the real-life environment of space, the pollution of Earth orbit with too many satellites and space junk, the scenario of “Kessler Syndrome” which provides the basis of the premise of the film, and the impact back on Earth of the space shuttle program, including pollution and habitat loss from launch facilities.

What exactly is Kessler Syndrome, how common are satellite collisions, and could a scenario like the one shown in this film really occur in real life? How many operational satellites are currently in orbit around the Earth? What was the space shuttle really built to do, and how come NASA didn’t end up doing very much of it despite 30 years and billions of dollars? Why did NASA have to build a manatee sanctuary in Florida? What did Sandra Bullock go through in order to film this movie? Why does Cuarón use so many fewer shots and cuts than most other directors? What did real astronauts think of the film? Is the Sandra Bullock character a strong female lead, or a damsel in distress? Can you believe how much she made from this picture? What other film, yet to be done on the Green Screen list, is Gravity most like, structurally? All these questions are heating up for fiery re-entry in this tropospheric episode of Green Screen.

Original 2013 trailer for Gravity. Warning: sudden loud sounds; don’t have your volume turned up.
In the opening scenario of Gravity, the crew of the space shuttle “Explorer” has their mission canceled and their ship shredded in a matter of minutes. This scene sets up most of the rest of the film.
Veteran astronaut Matt Kowalski (George Clooney), realizing he is pulling Ryan Stone (Sandra Bullock) off into space, sacrifices himself by detaching this tether. This is just one of the emotional wallops in Gravity.
After a harrowing traverse to a Russian space capsule, Stone appears to have an encounter with Matt Kowalski. Is he really there, or is her subconscious mind trying to tell her something?
The harrowing and emotional re-entry scene from Gravity. SPOILER ALERT: this is almost the conclusion of the film. Don’t watch if you don’t want to see how it ends.
