Terry Southern was integral to the avant-grade in postwar Paris, the Beat Years, swinging London, New York and Hollywood in the psychedelic sixties. He wrote the screenplays for Easy Rider , Dr Strangelove and Barbarella , suggested to Stanley Kubrick that he film A Clockwork Orange , and created some of the most enduring landmarks of popular culture. A Grand Guy tells Southern's story -- from his experiences during the Second World War to his appearance on the cover of Sgt. Pepper , from the lecture halls and jazz clubs of 1940s Paris to touring Texas with the Rolling Stones -- providing a fresh portrait of one of the most enigmatic icons of the twentieth century.
