Looking through a child's eyes and knowing this was another planet, we decided to design the machines with eyes and bodies like animals, we also decided that this planet has two moons, and we decided that anything else we wanted to do was allowed. It was a new perspective to make the film.

At the end of the process we called a market research company to find out whom the film was for or what was the target audience. We didn't have a lot of money to release the film, so in order for it to play in cinemas, which are dominated by films with much larger marketing budgets, we had to discover whom the film was for.

We discovered this halfway through the process. When we started making the film there were some lines of dialogue in Portuguese, but we then changed our minds. The film started from very specific issues in the world, in particular Latin America, but halfway through the journey we felt the necessity to have more universal ideas that were not so specific.

The film [Boy and the World]gave me the possibility to create a new language. Animation is a very rich medium but hasn't fully been exploited by artists. Often artists are trapped by words.

From what type of software could help us make a movie faster to everything else regarding the textures. Some might think, "It's probably very easy to make a film with those textures," but it's much more difficult than what it appears to be. We had to discover a faster process because otherwise it could have taken us 10 years to make it.

I always told my team, "You have to believe that you are not in front of a computer, but that your canvas is a piece of paper. You have to believe this even if you have a computer in front of you."

I tried to exploit such freedom to create those drawings like if I was a boy. I tried to draw with that freedom and that love that I remember from being a child and spending a day drawing without worrying about whether what I'm drawing is real or strange.
