8. Buster Keaton
Notable Roles: The General (1926); Sherlock Jr. (1924); Cops (1922); Neighbors (1920)
Getting his start in vaudeville, Buster had an unrivaled poker face. Seamlessly taking his charisma from the stage to the movie studio is what made him such a success back then, though we love him now for his flawless execution of interwar suiting-vests and peak lapels abound and nary a pocket without a square puffing out.
