Charlie Chaplin knew the great power of ridicule. Being a strong opponent of racism, in 1937 Chaplin decided to make a film on the dangers of fascism. As Chaplin pointed out in his autobiography, attempts were made to stop the film being made: “Half-way through making The Great Dictator I began receiving alarming messages from United Artists. They had been advised by the Hays Office that I would run into censorship trouble. Also the English office was very concerned about an anti-Hitler picture and doubted whether it could be shown in Britain. But I was determined to go ahead, for Hitler must be laughed at.” (Charles Chaplin, My Autobiography- 1964)
