William Sidney Stanton (September 18, 1885 – December 18, 1969) was an American character actor, whose career spanned the first twenty-five years of the sound film era. Stanton broke into the film industry at the very tail end of the silent film era in 1927, appearing in several film shorts for Hal Roach Studios. He would debut in a feature film with a small role in Raoul Walsh's 1928 silent film, Sadie Thompson, starring Gloria Swanson, Lionel Barrymore, and Walsh. During the following 20 years he would appear in another 70 films, mostly in small and supporting roles.
