About Mrs. Leslie is a 1954 American drama film directed by Daniel Mann and starring Shirley Booth and Robert Ryan.

She had a longtime but mostly platonic affair with the mysterious, lonely aviation industrialist George Leslie, who had originally hired her as a vacation companion on a trip to California.

Though they enjoy each other's company annually at a peaceful oceanside retreat, George tells Vivien nothing of his life until she accidentally learns of his career and marriage.

Vivien's neighbors and tenants include a young couple aspiring to television success and a dimwitted teenage girl.

[3] In a contemporary review for The New York Times, critic A. H. Weiler called the film "a somewhat lengthy tale, cluttered by some distracting flashbacks" and "a memory book that is only occasionally arresting."
