Borja Cobeaga's new comedy stars Manu Aranguren, a Basque politician who acts as a mediator for the Spanish government in its negotiations with ETA. Far from being a solemn, calculated occasion, unexpected occurrences, slip-ups or misunderstandings soon kick in to influence the dialogue. Ramón Barea, Carlos Areces and Josean Bengoetxea headline the cast.
Borja Cobeaga combined his work as a television director (first season of Vaya Semanita in 2003 on ETB) with directing and writing short films such as La primera vez (2001) and Éramos pocos (2005), winners of more than 100 international awards plus a Goya and an Academy Award nomination respectively. Prior to Negociador, he directed the feature films Pagafantas (2009) and No controles (2010), in addition to the short films Limoncello (2007), Un novio de mierda (2010) and Democracia (2013). He also co-wrote the films Amigos (2011) and 8 apellidos vascos (Spanish Affair, 2014).
