Gaslight

Director Thorold Dickinson memorably captures the stifling Victorian claustrophobia, and catapulted Walbrook into leading man status. His villain is one of the most chilling in movie history...

Bergman's portrayal of Paula Alquist, a woman slowly succumbing to the cruelty and isolation inflicted upon her fragile psyche by her husband Gregory Anton (...), gives her the chance to suffer gloriously for the film's duration.

The climax is a workmanlike rise of psychological terror, but the whole exercise looks self-consciously careful.

...[a] brilliant and beautiful psychological thriller from studio workhorse George Cukor.
