Terry Southern was integral to the avant-garde 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.
