Aitor Arregi and Jon Garaño direct the actors Eduard Fernández, Nathalie Poza and Sonia Almarcha, among others, in the film Marco, with music by Aránzazu Calleja.
Enric Marco Batlle was a Spanish trade unionist who served as Secretary-General of the National Confederation of Labour (CNT) and as president of the Amical de Mauthausen in Spain. During his time at the head of the Association, Marco gave a large number of talks, mainly in educational institutions, about his alleged experience as a survivor of the Nazi camps. Later, it was discovered that he had falsified data from his biography to appear as a survivor of the Flossenburg concentration camp during World War II.
