Netflix has started production on The Night Marta Disappeared, a six-episode miniseries based on the 2009 disappearance and murder of 17-year-old Marta del Castillo, a case that became one of the most closely followed criminal investigations in Spain and remains unresolved in key ways. The project is produced by Netflix alongside Bambú Producciones and La Claqueta PC. The cast includes Blanca Portillo, Vicente Romero, Verónica Sánchez, María León, Paco Tous, and Hugo Welzel.

Marta del Castillo disappeared on January 24, 2009, after leaving her home in Seville to meet Miguel Carcaño, her former boyfriend at the time. The case quickly escalated beyond a missing persons investigation as conflicting accounts emerged during questioning.

Carcaño gave multiple, conflicting accounts of what happened after their meeting, including different explanations about where Marta’s body was taken. Investigators carried out searches based on those accounts, but Marta’s body was never found. He later confessed to the killing and was convicted of murder. Several other individuals were also investigated in connection with the case.

The series follows the timeline of the disappearance, the investigation, and the search for Marta’s body and the events that followed, along with the shifting accounts that defined the case and the public attention that followed. The Night Marta Disappeared was created by Ramón Campos, Gema R. Neira, Salvador S. Molina, Curro Serrano, and David Orea Arribas, and directed by Carlos Sedes, Laura Alvea, and José Ortuño, with the support of Marta del Castillo’s family.

Coverage around the Marta del Castillo case became a story in itself, with Spanish media closely following each development as the investigation unfolded and continuing to report on new findings and developments more than a decade later.

The Night Marta Disappeared is currently filming in Seville as part of Netflix’s slate of scripted series based on real cases.
