[6] Vaughn frequently played a "pleb", or a commoner, in the films she acted in (waitresses, maids, charwomen, governesses, and saleswomen).
Her most notable films were 1933's Dinner at Eight where she was memorable as Jean Harlow's blackmailing maid, as well as Today We Live (1933), Chasing Yesterday (1935), and Charlie Chan at the Wax Museum (1940).
[7] She appeared on Broadway, and in 1924 toured as the lead in Rain based on a story by W. Somerset Maugham.
Her "smoldering quality" came back to Broadway two years later in The Seed of the Brute at the Little Theatre.
She returned to the stage in 1942 to play the lead in Only the Heart at the American Actors Company.
