Gravity visual effects

Gravity is 2013 special effects film, I have seen it in Broadway. The 3D effects is perfect but the realistic effects made me dizzy after 30 minutes watching. When I watch this film there is a question to my mind. This film should not be shot in the universe, but how to make weightlessness on earth. I have read plenty of reports on the internet, belowing is the answer of the question.

In every universe thematic film, present weightlessness is the hardest point. To achieve the agravity, there are two methods, one is use specialize plane named The Vomit Comet, with the high speed flight, this plane can create seconds of weightlessness. Apollo 13 is shoot in this way. However, this plane can not satisfy Gravity. Cameron require minutes of weightlessness effects. Therefore, Gravity crew come out an conventional entertainment combined with advanced digital technique. They use large-scaled puppet to manipulate actor’s body, to immerse weightlessness action. Cameron mentioned in a interview about the most difficult shot is the actress back to the capsule, she take off her spacesuit and huddle herself like a baby. In real scene, the actress was sitting in a small bike saddle to support her body; one leg was tied up with a special facility to fix her position. So the slow motion is controlled by puppeteer. The tied up leg was added by post-production.

Making an CG film is a test of filmmaker’s patience and technique, within CG film, everything could be possible.
