By the early 1920s, Chaplin was making his own films with actors Mary Pickford and Douglas Fairbanks due to the establishment of Chaplin Studios and United Artists in 1919. Having control of his own films lead to classics such as 'The Kid', 'The Gold Rush', 'City Lights', 'Modern Times' and 'The Great Dictator'. These films made him the most popular and successful film star of his time. Chaplin was accused of being a communist by Senator McCarthy, and a file was produced that supposedly detailed his subversive political activities since 1922. His first 'talkie' 'The Great Dictator' in 1940 added heat to this accusation and caused a stir. The film saw Chaplin play a caricature version of Adolf Hitler, which was seen as being in bad taste.
