The daughter of French refugees, Gigi Perreau was born within a stone's throw of Hollywood. Registered with Central Casting as an infant, 18-month-old Gigi played Eve Curie as a baby in 1942's Madame Curie, and at two played young Fanny (who grew up to be Bette Davis) in Mrs. Skeffington. As soon as she was able to talk, Gigi was being groomed by her managers as a potential Margaret O'Brien replacement. A little less mannered and more versatile than O'Brien, Gigi was at her best in such roles as Ann Blyth's irksome kid sister in My Foolish Heart (1950) an emotionally disturbed murder witness in Shadow on the Wall (1950), and a yet-to-be-born child shopping around for suitable parents in the 1950 comedy/fantasy For Heaven's Sake (1950). As her film career faded, Perreau flourished briefly as a TV leading lady, with supporting roles on the 1959 sitcom The Betty Hutton Show and the 1961 adventure weekly Follow the Sun. Adult stardom eluded her however, and by 1967 she was retired. Gigi Perreau was the sister of two other juvenile performers, Janine Perreau and Richard Miles; in the early 1960s, Perreau and brother Richard managed a popular Los Angeles art gallery.
