The Blue Flame is a four-act play written by George V. Hobart and John Willard, who revised an earlier version by Leta Vance Nicholson. In 1920, producer Albert H. Woods staged the play on Broadway and on tour across the United States. Ruth Gordon, the main character, is a religious young woman who dies and is revived by her scientist fiancé as a soulless femme fatale. She seduces several men and involves them in crimes, including drug use and murder. In the final act, her death and resurrection are revealed to be a dream. The production starred Theda Bara, a popular silent film actress who was known for playing similar roles in movies.

George Vere Hobart (1867–1926) was a Canadian-American humorist who authored more than 50 musical comedy librettos and plays as well as novels and songs. At the time of his death, Hobart was "one of America's most popular humorists and playwrights". Hobart gained initial national fame for the "Dinkelspiel" letters, a weekly satirical column written in a German-American dialect. The Library of Congress includes several of his songs in the National Jukebox.
