Bigas and Luna are two family backgrounds and two ways of approaching the world. The cinematic output of Juan José Bigas Luna (Barcelona, 1946 - la Riera de Gaià, 2013) recreates dualities: reality and desire in Bilbao, (1978), nature and culture in Caniche, (1979), religion as an experience and religion as speculation in Reborn, (1981), north and south as different cultures in Lola, (1986), fiction and reality in Angustia, (1987), normal and depraved aspects of sex in Las edades de Lulú, (1990), or the two sides of the Spanish male in Jamón, jamón (1992). Similarly, his artistic work displays assemblages of narrative rhythms and personal alchemies mixing film, painting, writing, photography, science and technology.
