"It has come a long way since then and has become a reality thanks to the combined commitment of Movistar+, Arte, Banijay Rights, Atlantique Productions and all their respective teams," said Alfonso Blanco, executive producer at Portocabo.
"We could not have asked for better partners for such an ambitious co-production,” he added.
The production teams behind Hierro
The series, which began filming last May
, will premiere in Spain on Movistar+ in the first half of 2019. It will also air on Arte in France.
Olivier Wotling, Director of Fiction, Arte, said: "Arte is proud to participate in the international co-production of Hierro. After developing projects in Norway, Denmark and, more recently, Germany and Italy, we are delighted to continue our European co-production journey with a Spanish project."
"The high quality scripts, combined with the complex characters and the backdrop of magnificent landscapes, instantly appealed to us."
Olivier Bibas, Executive Producer, Atlantique Productions, added: "Hierro is a further step forward in our ambition to produce European TV series with a strong local component that also have the potential to travel around the world."
"Atlantique Productions, together with Portocabo, led by Alfonso Blanco, is an excellent example of European collaboration. We are very happy to be producing this series for Movistar+ and Arte France."
The series stars Candela Peña
The company will be responsible for Hierro's international rights outside France, Germany, Spain and Latin America.
"From the first time we saw Hierro, we immediately knew we wanted to be a part of it. With electric storytelling and premium production values, this character-driven drama is set to be a hit with international audiences," said Caroline Torrance, Director, Scripted at Banijay Rights. She also said the drama will become a hit for international audiences.
Created by Pepe Coira and directed by Jorge Coira, Hierro begins when a hidden corpse with signs of a brutal murder is brought up to the sea surface in El Hierro, a small island of volcanic origin. Diaz, a dark local entrepreneur, is sent to prison as the main suspect.
Candela, a forceful, high tempered judge, sanctioned and banished to El Hierro, makes her first decision: releasing Diaz on bail.
The series is set on the most remote and untamed island of the Canary Islands
This very unpopular choice triggers the islanders' mistrust. Candela strongly believes she must do her duty above all else; meanwhile Diaz is out to get the culprit, prove his innocence and find out who has set him up, no matter what it takes. They both set out on a physical and emotional trip to hell.
It stars Argentine actor Dario Grandinetti and Spanish actress Candela Peña, and will have eight, 52-minute episodes.
