When the child Fernandito talks with Agustín in the living hall, it can be seen behind Fernandito the scene of a movie that Agustín is watching on TV. The scene belongs the previous Santiago Segura's movie ¡A todo tren! Destino Asturias (2021), where actor Antonio Resines, playing himself, was trying to film a commercial. Resines was the first choice to play Agustín, but he was unavailable because Resines was hospitalized after complications with Covid19, being replaced by Carlos Iglesias. Dedicated to him Segura credited Resines in the cast as "No sale pero le queremos", which translates as "He isn't but we love him".
The character of child Cristina (Cris for short) is played by two different actresses, Luna López and Candela Haro. López is credited as "Cris" and Haro as "Cris...a veces", which translates as "Cris...some times".
Seventh collaboration between Santiago Urrialde and Santiago Segura. Urrialde played a different role in each one of the five movies of Torrente franchise, and a taxi driver in ¡A todo tren! Destino Asturias (2021).
Roberto D'Antiochia, who plays briefly "Vecino 3", is Martina Valeria de Antioquía's father in real life.
