Trivia about The Crystal Cuckoo

The adaptation began when Netflix expanded its collaboration with Javier Castillo to bring his newly published novel The Crystal Cuckoo to the screen.

Filming took place across several locations, and some interior scenes were shot at Estudios Auriga in Hervás.

Filming began in October 2024 and wrapped in March 2025 after shooting in Extremadura and the Community of Madrid, according to Netflix's announcement of its completion.

Javier Castillo followed the adaptation closely during production and explained that he paid especially close attention to the story, although he did not take part in the filming in Hervás and Béjar on a constant basis.

The series consists of six episodes and is produced by Atípica Films for Netflix; the television adaptation was handled by Jesús Mesas and Javier Andrés Roig.

Production involved residents of Hervás during the months when the town became one of its main filming locations.

Filming also took place in Béjar, in Salamanca, as well as various locations in the Valle del Ambroz region of Cáceres.
