Rossen was one of the Directors who developed film gris (French for "grey film"). In his films for Warner Brothers' between 1937 and 1944, consistent themes were the conditions of working people, the portrayal of Gangsters and racketeers, and opposition to fascism. After Dust Be My Destiny, written by Rossen and released in 1939, Frank Nugent, who regularly reviewed for The New York Times, complained about Warner Brothers' long line of melodramas about boys from poor neighbourhoods. Unlike filmmakers such as John Ford and Howard Hawks, Rossen was willing to explain his aims as a director: "The element Common to many of my films is the Desire for success, ambition, which is an important element in American life. It is an important element, and has become increasingly more important in what is known as Western Civilization." Polonsky commented that "Rossen's talent is force applied everywhere without let-up." Neve acknowledged that social concerns were central in most of Rossen's works, but commented that Lilith was different from Rossen's earlier films as it emphasized mood rather than narrative and examined through pictures and silences the nature of maladjustment and madness.
