Betty Ross Clarke

Throughout her career, Clarke often performed on both the theater stage and in films during the same time period. A newspaper advertisement in 1922 noted that audience members could "see her on stage and screen at the same time," because she was performing in the play The Morning Him and also starring in the film At the Sign of the Jack O'Lantern. Commenting on the difference between stage and film acting, Clarke remarked that the "silent drama affords an easier life to those who choose it, for one has the nights free, to do as one likes. On the boards an actor's or actresses's time is always taken up."

Most of the silent films in which Clarke appeared have not survived. However, the films If I Were King and Mother o' Mine are preserved in the silent film archive of the Library of Congress. A print of Mother o' Mine is also housed in the UCLA Film and Television Archive. The silent film Traveling Salesman, with Roscoe "Fatty" Arbuckle in the leading role, can be found in the George Eastman House Motion Picture Collection in Rochester, New York. Many of the later sound films in which she appeared are still available, including Murders in the Rue Morgue, A Bride for Henry, Love Finds Andy Hardy, Judge Hardy's Children, and Four Wives.
