Gaslight is a 1944 MGM suspense thriller set in 19th Century London in which the villain, Gregory Anton (Charles Boyer), in an attempt to cover up his crimes, actively tries to convince his new wife, Paula (Ingrid Bergman) that she is losing her mind. Gaslight gave it’s name to the practice known as Gaslighting.
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.
