In “War Material,” Ruiz Capillas inherits a box of 6,000 negatives, mostly from the Spanish Civil War, that have never been developed or seen. As he brings them to light in the present, Ruiz Capillas’ mother, 88, is losing her memories to Alzheimer affliction. The Spanish Film Previews were supported by Spain’s ICAA film agency, in collaboration with trade and investment board ICEX. “What begins as a musical encounter becomes something very different,” Zapata (“La Singla”) said at the Spanish Film Previews before introducing 15 minutes of excerpts from the film. There will be a collective Alzheimer, a dissolution of everything lived,” Ruiz Capillas told Variety at Locarno.
