Operación H
In 1963, the businessman Juan Huarte Beaumont, art patron, collector and founder of X Films, a film production company based in Madrid, invited the Basque artists Nestor Basterretxea and Jorge Oteiza to make a promotional short about his companies. Certain conditions were attached to the commission: the artists were each to present finished scripts without any contact with each other about them. Huarte chose Basterretxea's script, and Basterretxea directed the film, which was given the title 'Operación H' in postproduction.
