Wim Wender’s latest documentary, Salt of the Earth, looks at the life and work of Brazilian photographer Sebastiao Salgado. Salgado is known for his images of war and poverty. And White God, by Hungarian director Kornél Mundruczó , is about Hagen, a mixed-breed dog who leads an uprising against careless humans. Both films open this weekend in Chicago. Film Contributor, Milos Stehlik, tells us why they’re both worth seeing. PHOTO: (Sebastiao Salgado)
