Dennis Dugan, credited as "Director Película", is a real-life American filmmaker. He directed Santiago Segura in the comedy Jack et Julie (2011).
Antonio Resines, who played Toño in the movie, was the first choice to play Agustín in Padre no hay más que uno 3 (2022), but he was unavailable because Resines was hospitalized after complications with Covid19, being replaced by Carlos Iglesias. Santiago Segura dedicated to him the movie crediting him in the cast as "No sale pero le queremos", which translates as "He isn't but we love him". Segura and Resines worked together previously in La fille de tes rêves (1998), Mort de rire (1999), Torrente 2: Misión en Marbella (2001), El oro de Moscú (2003), ¡A todo tren! Destino Asturias (2021), De Caperucita a loba (2023) and Vacaciones de verano (2023).
Florentino Fernández plays a priest in the movie, as he did too in Padre no hay más que uno 2: La llegada de la suegra (2020). In Padre no hay más que uno 3 (2022) he played a different role as "Marido Vecina".
