Logan Roy, the morally bankrupt media tycoon at the center of HBO’s Succession, is just one of the many complex characters Brian Cox has played throughout his career. In this segment from Hell & High Water, Brian Cox talks about playing iconic historical figures like Winston Churchill and Lyndon B. Johnson, and the importance of understanding the historical and cultural context in which they lived. He also explains how actors have to suspend judgment of the characters they play, especially in order to understand the motivations of infamously evil people like the Nazi war criminal Hermann Göring.
