The Broadway Bubble (1920)

Adrienne Landreth, the wife of Geoffrey Landreth, is dissatisfied with her life of luxury and is estranged from her husband. Because she longs for a footlight career as a musical star, when she is offered an opportunity to star on Broadway by theatrical producer Fred Corliss, she persuades her twin sister Drina Lynn to come to New York and pose as Geoffrey's wife while she herself pursues a career. Drina, less fortunate than her sister, reluctantly agrees and Geoffrey soon notices that his wife has become more compassionate and understanding. Hoping for a reconciliation, Geoffrey persuades his wife to attend the theater, and by chance, selects Adrienne's show. Upon seeing her husband in the audience, Adrienne becomes so disoriented that she stumbles and falls from the top of a flight of stairs, injuring herself fatally. She dies in her dressing room, leaving Drina and Geoffrey to face future happiness.—AFI
