Stanley Tucci: Searching for Italy

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.

Inspired by musician and eco-philosopher David Rothenberg's book of the same title, this documentary explores the intriguing, charming, complex and often conflicting theories on why birds sing like they do and why humans are so attracted to the sound. The film features contributions from musicians including Laurie Anderson, Jarvis Cocker and Beth Orton; enlightening and often startling analysis from some of the world's most eminent birdsong scientists; a literary guide to birdsong in poetry; a bizarre birdsong-themed art 'happening'; the creation of a new musical composition from the Afro-Celt Sound System, entirely made up of manipulated birdsongs; and a strange musical duet at New York's Bronx Aviary, featuring humans and birds.

Documentary providing a rare glimpse into the life of Alan Bennett, one of the UK's best-loved writers, with interviews, archive footage and new work.

Documentary revealing just how dangerous too much fat is to our most vital internal organs. The programme follows a specialist pathology team as they conduct a post-mortem on the body of a 17-stone woman whose body was donated to medical science. Their findings, as they dissect the body and its organs, are startling, exposing the devastating impact of obesity with stunning visuals and fascinating medical facts. Morbid obesity reduces life expectancy by an average of nine years and is blamed for over 30,000 deaths in the UK every year. With 65 per cent of people already overweight or obese, this extraordinary film is a powerful contribution to the debate about fat, food, lifestyle and how the health service will cope with the growing obesity crisis.
