This documentary explores the legacy of one of the most notorious British sitcoms of all time. Launching alternative comedy onto our screens, the show made household names of its performers and writers and proved to be a huge influence, despite the BBC reportedly being baffled by what they'd commissioned back in 1982. Never before had a flagship comedy show contained so much violence, depravity and anarchy - it was a shot across the bow to mainstream comedians that things would never be the same again.

Sir David Frost traces the development of the sketch show over the last fifty years, from variety theatre to primetime television.
