Alice Terry! It was the age of Alices. IMDB:

Alice started as an extra in films at age 15. She worked in "Inceville" and would appear as several characters in 'Civilization (1916)'. In 1917, she would meet director Rex Ingram and they would marry in 1921. 

Also:

It was while she was working as an extra on The Devil's Passkey (1920) that Alice was first noticed, by director Erich von Stroheim. Sadly, her insecurity caused her to rapidly leave the Universal lot. She never even stopped to pick up her pay check.
