"The Great Dictator" was popular with audiences, becoming Chaplin's most commercially successful film. Modern critics have praised it as a historically significant film, one of the greatest comedy films ever made and an important work of satire. Chaplin's climactic monologue has frequently been listed by critics, historians and film buffs as perhaps the greatest monologue in film history, and one of the greatest recorded speeches of the 20th century. In 1997, it was selected by the Library of Congress for preservation in the United States National Film Registry as being "culturally, historically, or aesthetically significant"."The Great Dictator" was nominated for five Academy Awards – Outstanding Production, Best Actor, Best Writing (Original Screenplay), Best Supporting Actor for Jack Oakie, and Best Music (Original Score).
