Kirsty Young's castaway this week is the actor, Damian Lewis.

As part of the wave of British talent that's crashed onto America's shores in recent years his impact has made a deep impression on the creative landscape. His role as Sergeant Brodie in Homeland saw him win both an Emmy and Golden Globe and along with Band of Brothers, The Forsyte Saga and a long list of other credits, he now ranks as one of our most well recognised and highly regarded performers.

Things didn't always look so peachy: aged 11, and in the school production of Princess Ida, he forgot the entire third act and stood mute in front of a packed auditorium. Tellingly, rather than scuttling into the wings with shame he soldiered on and by 16 he knew performing was, more than anything, what he wanted to do.

He says, "I am a person who is ambitious. I'm ambitious to get the very best from every moment and even if that's just taking my children to the zoo ... I want it to be the best it can be.".

Kirsty Young's castaway is the Right Honourable Theresa May MP - the longest serving Home Secretary in fifty years.

For those who think her political lineage seems directly descended from the Iron Lady, Theresa May's metal has certainly been stress-tested in the past few weeks. She's apologised twice in parliament for having failed to appoint a suitable head to lead the historical child abuse inquiry; a minister in her department resigned, claiming working with her had been like "walking through mud". Then there has been the controversy over the non-vote on the European Arrest Warrant and finally news this week that 1 in 5 crimes are unrecorded.

Just as well that she has a reputation as a woman who knows her own mind and is willing to speak it. She famously said the Conservatives were perceived as the 'nasty party'. Her excoriating speech to the Police Federation dealt head on with long-term corruption and incompetence in their ranks and was received with stunned silence.

So unflinching, resilient, driven and, if a recent poll is to be believed, a popular choice among Conservative voters to be the next Prime Minister. She has, so far, remained tight-lipped on any ambition to lead her party.

She says, "I think you have to believe in what you're doing - that's key. If you do believe you are doing the right thing - that gives you resilience".

Kirsty Young's castaway this week is the poet John Agard.

His work is studied widely in British schools. He was the BBC's first poet in residence and along with WH Auden and Philip Larkin, he's a recipient of The Queen's Gold Medal for Poetry.

Born in Guyana he arrived here in the mid-1970s already playing with words like some people play with musical notes. If his style is often satirical, his subjects provide wincing realism - examining the scars of slavery or the historical myopia of a shared past judged solely through European eyes.

He says he believes that "the poet keeps us in touch with the vulnerable core of language that makes us what we are."

Kirsty Young's guest is former Royal Navy test pilot Captain Eric 'Winkle' Brown - the programme's 3000th edition.

The Fleet Air Arm's most decorated pilot, his life reads like a handbook in beating the odds.

Landing on a flight deck is acknowledged as one of the most difficult things a pilot can do. Eric Brown has held the world record for the most flight deck landings - 2,407 - for over 65 years. He was one of only two men on his ship, HMS Audacity, to survive a German U-boat bombing.

In a long and remarkable life he has witnessed first-hand momentous events in world history, from the Berlin Olympics in 1936 to the liberation of the Belsen concentration camp.

Flying, he believes, is in his blood. He originally climbed into the open cockpit of a Gloster Gauntlet as a child to sit on his father's knee. Thirty years later he would pilot Britain's first ever supersonic flight.

He says: "It's an exhilarating world to live in. There's always that aura of risk - you come to value life in a slightly different way."

Producer: Paula McGinley.

Kirsty Young's castaway this week is the fashion designer, Professor Wendy Dagworthy.

During her time as Head of Fashion at both Central St Martins and The Royal College of Art she has taught students who've gone on to great success - Stella McCartney, Erdem and Antonio Berardi among them. Her skill lies partly in understanding the significance of a well cut pattern or a nicely turned seam, but also the warp and weft of a notoriously fickle industry.

At just 23, she was the toast of the catwalks with her own label selling round the world and worn by the likes of Bryan Ferry, Boy George and Mick Jagger. Dubbed 'the high priestess of fashion', her creative talent, however, wasn't recession-proof and her business went under in the late 80's. Given that reinvention is the lifeblood of fashion it seems she was tailor made for a new direction; collecting her O.B.E. in 2011 for services to the fashion industry, she wore a Perspex hat designed by a former pupil.

She says, "we want students to take risks - like we did when we were younger. There were no set rules, there was no one to follow - you just did it yourself."

Producer: Cathy Drysdale.

Kirsty Young's guest is filmmaker and criminologist, Roger Graef.

Pioneering in his chosen subjects and style, for the past fifty years he has shone a spotlight on hitherto hidden areas of society and influenced the entire genre of modern day documentary making. His films on key institutions like the Police have not just helped change attitudes but policy too.

A New Yorker and Harvard graduate, he first came to Britain to study Shakespeare: his London debut as a theatre director was a Tennessee Williams' play. He soon realised that the drama and storylines of real life were where his heart and talents lay.

He says, "What I want on my gravestone is 'Here Lies Roger Graef - he made a difference ...' and people are telling me that I have. But I don't think about it because there's so much left to do."

Producer: Cathy Drysdale.

Kirsty Young interviews the composer Debbie Wiseman.

Her work is wide ranging, but her talents are most often employed in crafting lyrical, melodic scores for film and TV. Her credits include Land Girls, Judge John Deed, Haunted and Father Brown. Now a visiting Professor at the Royal College of Music, her unlikely introduction to the piano came at the age of 8 when she found a bashed up old instrument sitting in the corner of a hotel dining room.

Producer: Isabel Sargent.

Kirsty Young's castaway this week is the historian, gardener and diarist Sir Roy Strong.

He stormed the establishment in the 1960s - a proto-meritocrat, in possession of a sharp mind, fizzing ambition and a brown velvet frock coat.

An avowedly unhappy and clever child he turned first to history and then art for stimulation and solace, setting down a template for a working life that would lead him to be the youngest ever director of the National Portrait Gallery and, later, to run the The Victoria and Albert Museum. Such early success left him with a fundamental problem - having fulfilled his wildest dreams by the age of 38 - what was he to do with the rest of his life? He would go on to publish his diaries and together with his wife Julia, created a garden at his home in Herefordshire, the Laskett.

Producer: Cathy Drysdale.

Kirsty Young's castaway this week is the writer Sally Wainwright.

TV is her chosen medium and Last Tango In Halifax, Happy Valley or Scott & Bailey are watched by millions of viewers. Her ear for dialogue and talent for story-telling place her among the cream of small screen dramatists: she majors in whip-smart phrasing and plot lines that twist the innards with their tension, but never strain plausibility.

Her passion for every day drama was honed at her mother's knee: in the 60's and 70's as Mrs. Wainwright watched Coronation Street, young Sally tuned in too, developing an affinity with the power of the portrayal of language as it is spoken and life as it is lived. She would later go on to write for the show.

She says, "When I was seven I started writing down the things people said - it was something I just had to do. I think I was born with it - it's like being able to draw or paint."

Producer: Cathy Drysdale.

Kirsty Young's castaway this week is the conductor, Marin Alsop.

Music Director of both The Baltimore Symphony and The Sao Paulo State Symphony Orchestra, she is a maestro with a mission: music, she believes, is a powerful vehicle for social change.

She had the good fortune to be brought up in "a household that exuded possibility" and was filled with music - both her parents played professionally. She took up the piano aged two, swapped to the violin at 6 and then aged 9, saw Leonard Bernstein at work and made the decision that conducting would be her career. Much later she would go on to be mentored by the man who inspired her.

It bores her when interviewers ask why there aren't more women conductors - nonetheless her capacity to maximise the few opportunities she was given as a young woman making her way in an exclusively mans' world gives one a flavour of her indomitability. Her day-to-day job after all is working out how to convince 100 experts to do what she wants.

She says, "maybe it's being an only child: you want to bring people together and create this big family feeling, I don't know what it is but I always gravitated towards organising."
