Rebecca (1940)

A young woman is in Monte Carlo, working as a ladies' companion, when she meets the recently-widowered, and very wealthy, Maxim de Winter (Sir Laurence Olivier). They fall in love and get married soon thereafter. The de Winters take up residence in Maxim's family estate, Mandalay. Mrs. de Winter (Joan Fontaine) finds it hard to fit in. The presence of Maxim's deceased wife, Rebecca, seems to permeate through the house and Mrs. de Winter can't shake the feeling that she is constantly being compared to her, and that she is an interloper. Mrs. Danvers (Dame Judith Anderson), Rebecca's personal maid, also takes care to make things as uncomfortable as possible for the new Mrs. de Winter. Mrs. de Winter has the constant fear that memories of Rebecca will drive her and Maxim apart. Over time, she grows to know more and more about Rebecca.
