Young's acting career was short-lived, though she appeared in three films. Her debut role was as Berta Hubbard, sister of Mabel Gardiner Hubbard, in Irving Cummings's 1939 biographical film The Story of Alexander Graham Bell, opposite her sisters Loretta (as Mabel), Sally, and Polly Ann. She would later have bit parts in two other films: No, No, Nanette (1940), and Border Incident (1949), the latter of which starred her husband, actor Ricardo Montalbán, whom she married in 1944.
