The first scene establishes the dreary tone of the film. It is nighttime in London and a murder goes unsolved. The magnificent Ingrid Bergman portrays Paula, the niece of the deceased woman. After living ten years trying to forget the past, Paula returns to her house in London at the suggestion of her new husband, Gregory (Charles Boyer). "I've found peace in loving you," Paula says and decides with the help of her husband, she is ready to face the past. Fear is an essential element in the story. It seems the police cannot find a motive for the murder but when a new young assistant comes to Scotland Yard, he sees something that others did not notice or would not pursue. The murderer remains at large and his next potential victim has returned to the very house where the first murder was committed.
The cast's flawless talent makes the film absolutely unforgettable. Charles Boyer is exceedingly ominous as Paula's obsessive husband. As the high-strung wife, Ingrid Bergman gives an outstanding performance. She is startling and brilliant. Brian Cameron, played by Joseph Cotton, makes his appearance later in the film but is wonderful nonetheless. Watch for the emphasis on foreshadowing and the beautiful lighting achieved in Gaslight, as well as the particular attention to the many details that make it spectacular. George Cukor's fantastic direction of this intriguing and suspicious tale will keep you on the edge of your seat.
