At the presentation of this project, Isabel Peña stated: “We are going to tell this series from three points of view: the story of this Spanish mafia, the growth of a relatively unknown police unit, and finally, the women who arrive in Spain having been completely deceived. We are passionate about this trio of worlds because it is genuinely real. We are talking about Spain in the early 2000s, but, as we know, this situation is still very much alive today. We hope the series lives up to the commitment we have made to this story.”

El castillo is an original Movistar Plus+ production, created in collaboration with Caballo Films and Mafalda Entertainment. It is executive produced by Fran Araújo (Movistar Plus+), Nacho Lavilla and Eduardo Villanueva (Caballo Films), and Isabel Peña.
