The film was based on "the only two biographies written of this woman [Bocanegra]".[1]Ofelia Medina, who co-wrote the screenplay with Eduardo Casar, stated: "The documents are minimal, with very few pages; we totally respected what they say, but it was necessary to create an element of romance around Gertrudis, since nothing is known of her personal relationships".[1]
Mónica Miguel was cast as Bocanegra's unnamed Purépechananny (called "nana" in the film) who teaches Bocanegra the Purépecha language. In an interview, the actress commented on her character's overall importance: "And it is a very deep character, because it represents all the Purépecha race, with all its history, and hopefully more movies related to our culture, traditions and history will be made".[2]
In 1993, Gertrudis won the Ariel Award for Best Costume Design (Mara González and Xóchitl Vivo). It was also nominated for Best Supporting Actress (Angélica Aragón), Best Music Theme (Leonardo Velázquez), and Best First Work (Ernesto Medina).[4]
