Actor Philo McCullough began his movie career at the Selig Company in 1912. At first, McCullough specialized in light comedy roles, often playing cads and bounders. After a brief stab at directing with 1921's Maid of the West, he found his true niche as a mustachioed, oily-haired, jack-booted heavy. During the 1920s he appeared in support of everyone from Fatty Arbuckle to Rin Tin Tin. Talkies reduced him to such bit parts as the "Assistant Exhausted Ruler" in Laurel & Hardy's Sons of the Desert (1933) and Senator Albert in Frank Capra's Mr. Smith Goes to Washington (1939). One of his few roles of consequence in the 1930s was the principal villain in the 1933 serial Tarzan the Fearless. Philo McCullough remained active until 1969, when he appeared with several other silent-screen veterans in They Shoot Horses, Don't They?.
