Every production faces unexpected obstructions that require creative solutions and conceptual rethinking. What was an unforeseen obstacle, crisis, or simply unpredictable event you had to respond to, and how did this event impact or cause you to rethink your film?

The most unexpected—or the most difficult—part of the film was the uncertainty of when to finish filming it. Of course, it’s always very difficult to end the recording of a documentary. But this was a film that when we started, we didn’t know when it would be [finished], and that was the main question. When the day came, and Augusto was no longer communicating as before and we felt a change in his emotional state, I think that both Paulina and I realized when that moment was. It was very clear for us to be able to say, Here, we stop.”
