Season 21 - Episode Guide

Imagine presents a feature-length documentary about the making of U2's seminal album Achtung Baby.

Early in 2011, U2 returned to Hansa Studio in Berlin to discuss the making of Achtung Baby in this film directed by Academy Award winner Davis Guggenheim (It Might Get Loud, Waiting for Superman, An Inconvenient Truth). From The Sky Down was then selected to open the Toronto International Film Festival on 8 September, the first ever documentary to open the festival in its 36-year history.

Twenty years after the 1991 release of Achtung Baby, Davis Guggenheim traces the album's genesis using animation and previously unseen footage from Berlin and Dublin alongside interviews with the band as they reflect on what was a key chapter in their career.

'In the terrain of rock bands - implosion or explosion is seemingly inevitable. U2 has defied the gravitational pull towards destruction... this band has endured and thrived. From The Sky Down asks the question why.' Davis Guggenheim.

Artist Grayson Perry has been working behind the scenes at the British Museum to stage his most ambitious show yet: The Tomb of the Unknown Craftsman. Given free rein to choose whatever he wants from the Museum's vast collections, Perry has also produced some 25 new works of art, from his trademark ceramics to a working motorbike. Imagine follows Perry for more than two years as he creates his own imaginary civilisation at the heart of the British Museum.

Arts series. In Jennifer Lebeau's film, Simon and Garfunkel: The Harmony Game, Paul Simon and Art Garfunkel talk openly and eloquently about an extraordinarily creative period in their career - the making of Bridge Over Troubled Water. The story behind what was to become their final album has long been shrouded in rock and roll mythology and is told in gripping detail in these rare interviews. Archive footage is used to reveal technical breakthroughs and the emotional feelings the two artists had for each other.

Sir Alan Ayckbourn is often described as the world's most performed living playwright. Yet it is his popularity that has often led to him being overlooked as a serious dramatist in the UK. As he premieres his 75th play in his seaside theatre in Scarborough, Imagine sets out to discover why Ayckbourn is so popular, and a chorus of distinguished fans explain why he must be recognised as one of the great dramatists of our time.

Vidal Sassoon is more than a hairdresser - he created styles that defined a generation. Craig Teper's film charts the career of the man who invented the bob-cut and, over the course of more than fifty years, created one of the most recognisable brands in the beauty business.

The arts series takes a road trip round the desert state of Rajasthan, meeting musicians whose existence is under threat from the new India. They meet Bhopa bards who recite four-night-long epics in front ofhuge hand-painted scrolls, saffron-clad, chillum-smoking sisters, cross-dressers and Gypsy dancers who literally bend over backwards to pick up rupees.

With the rise of electronic books, is the final chapter about to be written in the long love story between books and their readers? Will the app take the place of the traditional book?
