We all knew the book well because it's the cult book in Latin America. For me, this was a sacred territory. I would not have ventured into it by myself.
The other aspect is that you become much more aware of the structural problems that pertain to that continent. You feel the need to act to try and solve them.
That's why I have always admired documentaries, because they open windows that can make you understand much better where you come from, much better than fiction, I think.
So I feel a responsibility to help first-time film-makers in Brazil, but also to increase the dialogue between film cultures which are really wonderful and so much closer to us than what we do see on our screens.
I come from a country and also a continent whose identity is in the making. We're a very young culture, and I think that things are not yet crystallised.
But I also think that the more you reason collectively about what the project should be at the beginning of the process, the more you can improvise later.
Also, there are now new laws in Brazil which create incentives for Argentine and Latin American films to be premiered and distributed in Brazil and vice versa.
Also, I knew that the impact of Motorcycle Diaries was going to be so resonant for all of us who went through the experience of making it that I didn't want to do anything that could reflect it.
The necessity to conceptualise has to come very early on, and defining a vector of development for that film also at the beginning of the process will allow you much more freedom as you go along.
The films that I've done before were original stories most of the time, I did two adaptations before this, but they were mostly original stories where I had complete freedom to evolve in the direction I wanted.
