Bewitched (1945)

In the midst of her joyous engagement celebrations, the seemingly ordinary Joan Ellis is confronted by the persistent, sinister voice that has echoed in her mind since childhood. This chilling whisper is not a spectral entity, but her own alternate persona - Karen, a cunning and malevolent woman growing progressively powerful, threatening to usurp Joan's existence completely. Joan finds herself in a precarious negotiation with her inner adversary, and despite reaching a tense agreement, Karen, as duplicitous as she is dangerous, breaks her promise when opportunity knocks. Her insidious ambition? To claim the affections of the men Joan holds dear - her affianced, Bob Arnold, and Eric Russell, a charismatic lawyer encountered in the bustling heart of New York City. With her life hanging in the balance, Joan is driven to desperate measures to expel Karen, even if it means endangering her own existence. Unaware of the true nature of Joan's torment, those in her inner circle, including Eric and the compassionate Dr. Bergson, scramble to rescue her from an unseen enemy. Their struggle forms the crux of this chilling tale, where internal chaos threatens to consume a life.

Bewitched is a drama movie featuring Phyllis Thaxter and directed by Arch Oboler.
