The film career of actor Louis Natheaux spanned 19 years (1921-1940). At first, the slender, mustachioed Natheaux was cast as pomaded city slickers and shifty-eyed con artists. After a burst of activity in the first years of the talkies, he was consigned to bit parts, usually as a jaded croupier or snap-brim-hatted crook. He played larger roles in the two-reelers of such Hal Roach comedians as Charley Chase, Thelma Todd, and Patsy Kelly, and was occasionally featured as murder suspects in Poverty Row mysteries like Sinister Hands (1932). Louis Natheaux was also an off-and-on utility actor for Cecil B. De Mille, essaying minor parts in King of Kings (1929), Union Pacific (1939), and Northwest Mounted Police (1940).
