imagine... - Season 26

As Brazil prepares to host the Fifa World Cup this summer and the Olympic Games in 2016, imagine... explores the cultural and social history of the city of Rio de Janeiro, home to more than six million Carioca.

A city of extremes, Rio is still seen by many as a tropical paradise, but it is also a city divided by class, ravaged by poverty and gun crime. With its roots and rhythms in samba, the music of Rio has directly influenced decades of social and cultural change.

imagine... journeys through an extraordinary city, illustrated and narrated by the music and voices of this Brazilian metropolis.

After Portnoy's Complaint launched him as a new literary voice, not to mention a scandalous one, Philip Roth went on to be hailed by many as America's greatest living writer. Never afraid to look hard at theextremes of human experience, he has been both consistently controversial and intensely private.

But now, having celebrated his 80th birthday in his home town of Newark, New Jersey, Roth, in conversation with Alan Yentob, is ready to tell the whole story in this special two-part film for imagine... Philip Roth Unleashed.

Alan Yentob talks to Philip Roth in the second half of a two-part film.

After his scandalous debut with Portnoy's Complaint, and the intensely personal novels of his early career, Philip Roth turned this samefearless vision to some of the great themes of the American century - civil rights, McCarthyism, the Vietnam war - as his characters become impaled on history.

In a career spanning six decades Roth became one of the most controversial and influential writers of the modern age, and only now, with the advent of his 80th birthday, is he ready to reveal all.

The five surviving members of Monty Python have spent the last 20 years dismissing a reunion as 'absolutely impossible'. Now, it seems, they've changed their minds...

In this special edition of imagine... Alan Yentob follows Cleese, Palin, Jones, Gilliam and Idle (collective age 357) as they pursue solo projects in far-flung locations, reflect on old age, and prepare for the shows in London that will bring the final curtain down on Python after 45 years.
