The Vixen (1916)

In this lost film, Theda Bara took the role of spoiled, deceiving nymphomaniac "vixen" Elsie Drummond. She wooed Wall Street businessman Martin Stevens (A. H. Van Buren) away from his interest in her sweet sister Helen (Mary G. Martin). She continued to seek after rich men, eventually marrying young statesman Knowles Murray (Herbert Heyes) (again stolen from Helen) - but still willing to be unfaithful with Stevens who had since regained his fortune.
