The quintessential silent screen villain, tall (6'1"), mustachioed Lloyd Whitlock is perhaps best remembered as one of the kidnappers in Mary Pickford's Sparrows (1926) and for playing innumerable blackguards in B-Westerns and serials of the 1930s and 1940s. Trained as a civil engineer, Whitlock toured with several stock companies prior to making his screen debut with New York's Biograph company in the very early 1910s. By the mid-1910s, he had become a featured actor for Kleine, Kalem, and Universal and was already more often than not cast as lecherous blackmailers, crooked lawyers, medical hacks, and the like. He made the transition to sound with ease but quickly began showing up in Poverty Row productions and is memorable as the airline manager in the John Wayne serial Hurricane Express (1932) and as the boss villain in four of Wayne's Lone Star Westerns for Monogram. Although his roles greatly diminished in importance from the mid-'30s on, Whitlock remained a busy supporting actor through the 1940s.
