Shirley Booth followed up her Oscar-winning performance in Come Back Little Sheba with the high-gloss soap opera About Mrs. Leslie. Based on a novel by Vina Delmar, the film casts Booth as a philosophical boarding house keeper who recalls her life and loves in a long, long flashback. Born on the wrong side of the tracks, Vivien (Booth) escapes her surroundings by becoming a cabaret singer. She meets and falls in love with handsome, secretive George Leslie (Robert Ryan), then becomes his mistress, assuming his last name in the interests of propriety. Upon Leslie's death, Vivien discovers that her lover was actually a fabulously wealthy industrialist. Her experiences are placed in context with the present-day travails of her boarders, notably young sweethearts Nadine (Marjie Millar) and Ian (Alex Nicol).
