The career of Alain Resnais (1922-2014) extended over more than six decades. After training as a film editor in the mid-1940s, he went on to direct a number of short films, which included Night and Fog (1955), an influential documentary about the Nazi concentration camps. Resnais adopted unconventional narrative techniques to deal with themes of troubled memory and the imagined past. His films frequently explore the relationship between consciousness, memory, and the imagination, and his narratives use innovative formal structures.
