The reality is that art has often risen to greater heights than the people who created it. Many flawed artists have created great works of art. You have to decide if you are going to listen to Richard Wagner's music or not because he was very anti-Semitic.
I worked initially in very low-budget independent films that I often wrote. My early work was all written by myself, and then I adapted 'Tsotsi,' so I was used to the writing process being, in a way, integral to my directing. I felt it really prepared me.
What's genius about 'Gravity' is that you are close upon the actors, but 3D works best when you have foreground, middle ground and background.
This may sound melodramatic but I have never, ever worked so hard. The film will be released in a different country every week for the next six weeks. I've just come back from Germany, France and Sweden to be in LA for the nominations and to speak to the American press.
