Gaslight (1944)

In the role for which she won the first of her three Academy Awards, Ingrid Bergman stars in this classic thriller as a devoted bride whose groom is trying to make her insane as part of his plot to murder her. Late 19th century Victorian England. Young Paula Alquist (Bergman--Casablanca, Indiscreet) has given up a promising singing career to marry Gregory Anton. Deeply in love, she refuses to believe--then cannot convince anyone else--that her new husband is a thief who murdered her aunt, that everyone in her household is plotting to kill her ... and that something evil will happen every time she sees a dimming of the Gaslight.
