At what point did they tell you about the story and what was your reaction?
Aparicio: So it was actually Alfonso at the last casting where I traveled to Mexico City to see him and he was the one who told me it was a very personal story and it was a story about his mother, but he actual meant he had two mothers. He had his own biological mother and then Libo, the woman on whom the film is actually based.
Were you familiar with Alfonso's work at all? Once you got the role did you watch all the films?
Aparicio: So at first he asked me if I had seen any of his work and I said no. He said, "Have you seen any of my films," and I said no, and he said, "Well, great actually. I don't want you to burden your mind with any of these things so I don't want you to watch any of them. If you want to watch them once we are done you are welcome to."
What was the preparation? Was there anything Alfonso wanted you to do? Anything you wanted to do yourself?
Aparicio: So initially he did not, for example, give me any kind of acting classes because he was interested in things being natural and not overacted. So what I actually just did was to embrace the character to behave and act as if I was Cleo. And allow the things that was happening as the shoot was going on to surprise me and react to them.
Did you get to spend any time with Libo at any time during the process?
Aparicio: I met her before the shoot. So what she told me was the same thing Alfonso told me, which had to do only with her past, where she had come from, how she had arrived to the city, how it was like to work with the family, but she actually stopped giving me information until the point where the film actually starts.
Why do you think she did that?
Aparicio: I don't know, but I would guess that because I was not trained as an actress they did not want that information in some way to influence the ways in which I would react to particular situations that would be presented as the film went on.
