Because no kid was right for the part, Derbez announced via Twitter that he needed a 100% bilingual kid for a new movie. Loreto Peralta saw the tweet and went to the casting. Although he was looking for a boy, Derbez loved Peralta instantly.

Eugenio Derbez admitted on TV that this project needed twelve years (since the original idea) to be concluded due to the specific detail of the movie he had in mind. As a result, he had to wait several years to get the money for it.
Eugenio Derbez "Valentin" and Julie's partner Alessandra Rosaldo "Renee" are actually married in real life and have a daughter, Aitana.
Loreto Peralta applied for the casting after a friend of her mother told her that Eugenio Derbez was looking for a girl pretty much like her daughter via social networks.
