The film is an Argentine and Spanish co-production by Tornasol Films, "Árbol Contenidos" [es], Haddock Films, Hernández y Fernández PC, and Mistery Producciones AIE, in association with Telefé and with the participation of TVE.[2][3] One of the actors, Pablo Echarri, also gave support with his company El Árbol, with this being his first foray as a producer. The director, who was in charge of the script, developed it in the course of five years in the Storyboard format.
All those involved in the production highlighted that, "Except for the two outdoors scenes, everything was recreated in studios: The protagonist's house, the basement where the robbers hide, and even the tunnel to real scale in a construction of fifty meters".
The main female role is played by the Spanish actress Clara Lago, (who was the protagonist of Ocho apellidos vascos and its sequel Ocho apellidos catalanes). Lago's character "Berta", speaks Rioplatense Spanish, which was achieved by the actress in a very short time. Rodrigo Grande explained this: "Clara arrived two weeks before shooting, and had a traditional accent. But two weeks later she was speaking Argentine Spanish. It was amazing ... She had a coach for only four days and then she handled herself".[4]
