In the States, I learned to fight for every idea. Sometimes, a director has to be a tyrant to keep the quality.

When I was a child, I had a ViewMaster, those red box glasses with little discs, so that you can see 3D images. They were my first steps in cinema. I was eight years old, I would cut and change the order of the images and that's how I created films that subsequently I recorded and projected and showed my friends. So I already took my first steps in 3D when I was eight years old.
