Gaslight is an American 1944 mystery-
thriller film adapted from
Patrick Hamilton's 1938 play
Gas Light about a woman whose husband slowly manipulates her into believing that she's going insane. It was the second version to be filmed, following the British film
Gaslight, directed by
Thorold Dickinson and released in 1940. This 1944 version was directed by
George Cukor and starred
Ingrid Bergman,
Charles Boyer,
Joseph Cotten, and 18-year-old
Angela Lansbury in her screen debut. It had a larger scale and budget than the earlier film, and lends a different feel to the material. To avoid confusion with the first film, this version was in the UK originally given the title
The Murder in Thornton Square.
