Robert Watson Knucher (1888-1965) started out in vaudeville as a teenager, and also toured the United States with a travelling medicine show. He moved up through appearing in shows at Coney Island, to a Broadway debut in 1918, where he continued to work.
Watson made his first film in 1925 in That Royle Girl, a minor work by D W Griffith. He went on to appear, usually uncredited, in around ninety pictures, including: China Seas (1935), Captains Courageous (1937), The Miracle of Morgan’s Creek (1943, and one of nine pictures in which he played Adolf Hitler), The Big Clock (1948, and a rare credited role as one of the employees at Janoth Publications), A Foreign Affair (1948, and Hitler again) and The Four Horsemen of the Apocalypse (1962, his last film and playing Hitler).
Bobby Watson acted in five MGM musicals, though he was credited only in the first, playing the press agent Thompson in Going Hollywood. The uncredited appearances were in Born to Dance, Singin’ in the Rain (as the diction coach in ‘Moses Supposes’), The Band Wagon and Deep in my Heart.
