New 4K Restoration. One of the great debuts in cinema history, Pedro Costa’s first feature film (shot when the director was just 29-years-old) is a stylish and atmospheric fairy tale about two young, impoverished brothers who make their own way in the streets of Portugal after their father’s death. Stunningly shot in black-and-white, O Sangue evokes the work of master filmmakers that influenced Costa (such as Fritz Lang, Kenji Mizoguchi, Robert Bresson, and Nicholas Ray) while also displaying his own emerging vision as a world-class auteur.
