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 a classic suspense thriller set in nineteenth-century London. In the movie, Paula (Ingrid Bergman) marries the villainous Gregory Anton (Charles Boyer), not realizing that he is the one who murdered her aunt and is now searching for her missing jewels.

To cover up his treachery, he tries to persuade Paula that she is going mad, so he can search the attic for the jewels without her interference.. He plants missing objects on her person in order to make her believe that she has no recollection of reality. He tries to isolate her, not allowing her to have visitors or to leave the house. However, she uncovers the truth when she notices the dimming of the gaslight.

From the movie, the term "Gaslighting" has come to mean any form of manipulating a person into believing something other than the truth.

Examples of Gaslighting:

  • A family member who steals something from you tries to convince you that it belongs to them.
  • A person acts threateningly, then accuses you of abuse when you react in self-defense.
  • A spouse tries to persuade you that you said or did something that you know is inaccurate.
