Paul Merton's journey through early Hollywood reaches the 1920s when in prohibition America the cinema industry was on a collision course with its public because of a run of drink, drugs and sex scandals.

Having cynically used the popular press to promote its stars and keep their reputations spotless, it now faced a media obsessed with exposing the dark and decadent side of their glamour.

The programme tells the story of the rise and fall of the lost comic genius of silent Hollywood - Roscoe 'Fatty' Arbuckle - who was charged with the murder of a young actress after an illegal drinks party went wrong. Paul Merton makes a powerful case that Arbuckle was an innocent man, an unfortunate victim of a new type of fame created by the Hollywood studios which had been turned against them. In their rush to clean up their act they were prepared to make the genial Arbuckle a sacrificial victim.
