[1] One of the original Keystone Cops,[3] Conklin wore makeup of heavy eyebrow lining and a thin, upside-down, painted-on variation of Kaiser Wilhelm's mustache.

In areas where anti-German sentiments still ran high during the post-World War I era, Conklin was billed as Charlie Lynn.

One of Conklin's first talking pictures was All Quiet on the Western Front as a hospital patient.

For the rest of his career in talking pictures, he had small roles in 2-reelers which starred The Three Stooges, Andy Clyde, Hugh Herbert and Harry Langdon.

Conklin's last billed movie was Abbott and Costello Meet the Keystone Kops.
