American actor Walter Walker had already enjoyed an extensive theatrical career by the time he made his first film appearance in 1917. From that point onward until his death in 1941, Walker played dozens of judges, wardens, governors, and college deans. In the talkie era, he was often as not cast as an old-timer, inevitably named "Pop." Among his many one-scene roles of the 1930s was Benjamin Franklin in MGM's Marie Antoinette. Walter Walker's credits should not be confused with those of bit player/extra Wally Walker (1901-1975).
