A tribute to British comedian Mel Smith, who died in July 2013, aged 60, featuring home video footage, rare archive material and many classic sketches. Far more than a comic actor, Smith also wrote and edited a host of celebrated TV comedies in the 1980s and 90s. He was a theatre and film director, and as a TV producer he was responsible for several innovative comedy series. Friends and colleagues, including Griff Rhys Jones, John Lloyd and Richard Curtis, talk about Smith's talents, both in front of- and behind the camera. The programme also traces his time at Oxford and, before that, Latymer Upper School, where Smith's talents were first spotted.

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.
