A leading man for the New York-based Excelsior company in the early 1910s, this supporting actor of many names was born Gordon de Main Wood. Later in his career, DeMain would alternately bill himself as Gordon De Maine, Gordon DeMain, Gordon Wood, G.D. Wood, or simply Bud Wood, but in the early sound era he would invariably play two of the mainstays of low-budget Westerns, either the Boss Villain or the Sheriff. Once in a while, he would emerge far down in the cast list of a Grade-A film, but then merely playing "Aide" (Mata Hari ) or "Man" (The Whole Town's Talking ). DeMain was always more at home on the range, either making life miserable for such stars as Bob Steele and Tom Tyler or helping them out of a scrape or two. DeMain continued in films until the mid-'40s, but in his later years he was mainly just a member of the posse.
