Using colour footage found hidden in suitcases at the Chaplin family villa, Timewatch presents a new analysis of the film The Great Dictator and recounts the parallel stories of Charlie Chaplin and Hitler - two men born in the same week. As the Nazi leader launched his blitzkrieg, Chaplin's satire of Adolf Hitler was near completion. By the time the movie arrived in England - at the height of the Blitz - it was regarded as the greatest tonic imaginable for the British people, and it went on to bank more than twice as much as any other Chaplin film.
