Gaslight (1944) 煤气灯下

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 is going insane.

The 1944 version 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. Gaslight 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 originally given the title The Murder in Thornton Square in the UK. This film features numerous deviations from the original stage play, though the central drama of a husband trying to drive his wife insane in order to distract her from his criminal activities, remains.

Years after her aunt was murdered in her home, a young woman moves back into the house with her new husband. However, he has a secret that he will do anything to protect, even if it means driving his wife insane.
