Walter Long was an American character actor in films from the 1910s.
He was born in Nashua, New Hampshire. He appeared in many D.W. Griffith films, notably The Birth of a Nation (1915), where he appeared as Gus, a Negro, in blackface make-up, and Intolerance (1916). But he is now best remembered for his roles in several Laurel and Hardy films in the 1930s as a comic villain.
While his on-screen persona was crude and thuggish, in his private life he was well-dressed, intelligent, and personable, the complete antithesis of the characters he portrayed.
