Joan Fontaine and her husband William Dozier produced this film which contains a classic performance for Fontaine. In it she plays a woman who sees a lot more in the character of the man of her dreams than he really possesses. The object of her affection is Louis Jourdan, a womanizing concert pianist who when the film opens up is about to flee the scene rather than face an irate husband in a duel. Just as he's ready to take it on the lam, Jourdan receives a Letter From An Unknown Woman, one of many he's known in his life. He reads and the story in flashback begins.
Like in her performance in The Constant Nymph Joan starts her performance as a child. When and widowed mother Mady Christians were living in Vienna, Jourdan was learning his craft and the sound of his playing gave her romantic fantasies.
Later on when they meet as an adult they do have a brief affair which leaves her with child. True to his nature he leaves her and pursues his career and his romantic avocations. She was barely a blip on his radar.
During the course of Fontaine's off screen narration of her letter, the tragedy of her life unfolds and the causes are a combination of her romantic fantasies and his lack of character. I can't say more but the end is truly heartbreaking.
Letter From An Unknown Woman was a nice and truly original idea. It starts slowly, but you really get drawn into the story by Fontaine's off screen narration and on screen performance. Jourdan too is fascinating as a man who is less than the sum of his parts.
A really great choice of roles for Joan Fontaine.
