Film gris ([film ɡʁi], French for "grey film"[1]), a term coined by experimental filmmaker Thom Andersen, is a type of film noir which categorizes a unique series of films that were released between 1947 and 1951. They came in the context of the first wave of the communist investigations of the House Un-American Activities Committee, often made by associates, fellow travellers and supporters of the convicted Hollywood Ten.[2][3]
