Gaslight

Gaslight is a 1944 psychological thriller film directed by George Cukor and starring Ingrid Bergman and Charles Boyer. The film follows Paula Alquist, a young woman who marries her accompanist Gregory Anton after a two-week whirlwind romance. They move into her late aunt's London townhouse, where Paula starts to experience strange occurrences that make her question her own sanity. As Paula's mental state begins to deteriorate, Gregory's behavior becomes increasingly suspicious. He convinces her that she is forgetful and careless, and isolates her from her friends and family. Meanwhile, Inspector Brian Cameron of Scotland Yard becomes interested in reopening the case of Paula's murdered aunt, and discovers that Gregory is not who he claims to be. The film builds up to a thrilling climax as Paula uncovers the truth about her aunt's murder and Gregory's true identity. With the help of Inspector Cameron, Paula exposes Gregory's sinister plot to drive her insane and steal her inheritance. The film's title refers to the gaslights that flicker and dim in the townhouse, which Paula believes are a sign of her own madness but are actually being manipulated by Gregory to further his deception. Gaslight was a critical and commercial success upon its release, and has since become a classic of the thriller genre. It won two Academy Awards for Best Actress (Ingrid Bergman) and Best Supporting Actor (Charles Boyer), and was also nominated for Best Picture and Best Director. The film has been remade several times, but the 1944 version remains the most iconic adaptation of this gripping tale of psychological manipulation.
