Gaslight is a 1944 American psychological thriller film directed by George Cukor, and starring Charles Boyer, Ingrid Bergman, Joseph Cotten and Angela Lansbury in her film debut. Adapted by John Van Druten, Walter Reisch, and John L. Balderston from Patrick Hamilton's play Gas Light (1938), it follows a young woman whose husband slowly manipulates her into believing that she is descending into insanity.

George Dewey Cukor was an American film director and producer. He mainly concentrated on comedies and literary adaptations. His career flourished at RKO when David O. Selznick, the studio's Head of Production, assigned Cukor to direct several of RKO's major films, including What Price Hollywood? (1932), A Bill of Divorcement (1932), Our Betters (1933), and Little Women (1933). When Selznick moved to Metro-Goldwyn-Mayer in 1933, Cukor followed and directed Dinner at Eight (1933) and David Copperfield (1935) for Selznick, and Romeo and Juliet (1936) and Camille (1936) for Irving Thalberg.
