Ulises Pérez Aguirre

And I took it from there.

I took over, I continued the research thanks to the information he kindly provided to me, and I made a call to the Cineteca, and they told me, well, Alejandro, the movie is here, but this is not something, the material doesn't belong to the Cineteca, but it does belong to the family of Ulises Pérez Aguirre, which you know is the producer.

So they gave me the contact information of the daughter, Andrea Perez Mata, her phone number and an email.

And I wrote her an email.
