Alain Resnais (3 June 1922 – 1 March 2014) was a French film director and screenwriter whose career 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 began making feature films in the late 1950s and consolidated his early reputation with Hiroshima mon amour (1959), Last Year at Marienbad (1961), and Muriel (1963), all of which adopted unconventional narrative techniques to deal with themes of troubled memory and the imagined past. These films were contemporary with, and associated with, the French New Wave (la nouvelle vague), though Resnais did not regard himself as being fully part of that movement. He had closer links to the "Left Bank" group of authors and filmmakers who shared a commitment to modernism and an interest in left-wing politics. He also established a regular practice of working on his films in collaboration with writers previously unconnected with the cinema such as Jean Cayrol, Marguerite Duras, Alain Robbe-Grillet, Jorge Semprún and Jacques Sternberg.
