"Suzanne Cupito was among the busiest child actresses in the business in the 1950s and 1960s. Suzanne was generally cast in spoiled-brat roles or essayed the "leading lady as a child" in such films as Gypsy (1963) and Marnie (1964); along with Billy Mumy, she held the distinction of being one of the few actors under the age of 13 to appear in three Twilight Zone episodes. After a long fallow period in the 1970s, Suzanne Cupito reemerged as bewitchingly beautiful leading lady Morgan Brittany. Her remarkable resemblance to actress Vivien Leigh enabled Morgan to portray Ms. Leigh in several films, notably Gable and Lombard (1976) and the made-for-TV The Scarlet O'Hara Wars. Morgan Brittany's series-TV resume includes three seasons as Katherine Wentworth on the nighttime serial Dallas." More about Morgan Brittany at allmovie
