Satire (1922), "Elmer Gantry" (1927; dedicated by Lewis to H. L. Menchen), and "It Can't Happen Here" (1935), and his books often explored and satirized contemporary American values. The film "The Great Dictator" (1940) by Charlie Chaplin is itself a parody of Adolf Hitler; Chaplin later declared that he would have not made the film if he had known about the concentration camps. In the United States 1950s, satire was introduced into American stand-up comedy most prominently by Lenny Bruce and Mort Sahl. As they challenged the taboos and conventional wisdom of the time, were ostracized by the mass media establishment
Charlie Chaplin portrayed by Robert McClure in both productions. In 2013, two plays about Chaplin premiered in Finland: "Chaplin" at the Svenska Teatern, and "Kulkuri" ("The Tramp") at the Tampere Workers' Theatre. Chaplin has also been characterised in literary fiction. He is the protagonist of Robert Coover's short story "Charlie in the House of Rue" (1980; reprinted in Coover's 1987 collection "A Night at the Movies"), and of Glen David Gold's "Sunnyside" (2009), a historical novel set in the First World War period. A day in Chaplin's life in 1909 is dramatised in the chapter titled "Modern Times" in Alan Moore's "Jerusalem"
