Blithe Spirit (1945)

To get background for a new book, author Charles Condomine (Sir Rex Harrison) and his second wife Ruth (Constance Cummings) light-heartedly arrange for local mystic Madame Arcati (Dame Margaret Rutherford) to give a séance. The unfortunate result is that Charles' first wife Elvira (Kay Hammond) returns from beyond the grave to make his life something of a misery. Ruth too gets increasingly irritated with her supernatural rival, but Madame Arcati is at her wit's end as to how to sort things out.
