These days he's starring in the West End in the comedy One Man, Two Guvnors. It is due to transfer to Broadway in the spring and he says: "I'm well aware that this could well be the best part that I ever play on stage - it's a gift for any actor who has any interest in comedy. It feels like all my dreams come true."

Denise Lewis, Olympic gold medallist, is Kirsty Young's castaway.

Her discipline was the heptathlon and it was at the 2000 Sydney Olympics that she leapt, threw, sprinted and hurdled her way on to the winner's podium. An only child of a single mother, she says her mum had always had ambition for her - and was there to witness her success. She said: "Her face said it all, there were tears in her eyes and for me it felt like, yes mum, we've done it together".

Kirsty Young's castaway for the 70th anniversary edition of Desert Island Discs is Sir David Attenborough.

He has seen more of the world than anyone else who has ever lived - he's visited the north and south poles and witnessed most of the life in-between - from the birds in the canopies of tropical rainforests to giant earthworms in Australia.

But despite his extraordinary travels, there is one part of the globe that's eluded him. As a young man and a keen rock-climber, he yearned to conquer the highest peak in the world. "I won't make it now - I won't make it to base camp now - but as a teenager, I thought that the only thing a red-blooded Englishman really should do was to climb Everest."

Kirsty Young's castaway is the author Vikram Seth.

His novel A Suitable Boy was nearly a decade in the writing, but it was a huge and immediate hit and won the Commonwealth Writers' Prize. He is now working on a follow-up novel called A Suitable Girl. He's due to finish work on it in 2013 - 20 years after the original work was published. The pace of work, he admits, is slow: "The sound of deadlines pushing past is one of the sounds that authors are most familiar with - it's very much in the gestational period."

Kirsty Young's castaway is the writer and historian Paul Johnson.

He writes, he says, out of a desire to 'put things right' and more than fifty books and thousands of articles have flowed from his pen. His opinions have provoked, offended and enraged plenty of people over the years and sweeping works about modernity, morality, art and philosophy, sit alongside fiercely opinionated biographies and essays. He says: "I like to be, in general, in agreement with what most people think, but I also like to be a little bit independent and individual and, thank God, I've been allowed to do that all my writing life."

Kirsty Young's castaway is the director of the Royal Ballet, Dame Monica Mason.

Her working life has been dedicated to dance. When she joined the Royal Ballet at fifteen she was the youngest dancer to be admitted to the company and, during her career, its legendary choreographer Kenneth MacMillan created five roles for her. She became director ten years ago and is due to step down this summer. She says: "I couldn't bear it if I thought that, behind closed doors, somebody was saying 'she's here again, you know', so I shall keep my distance and only go in when asked."

Kirsty Young's castaway is the broadcaster Sir Terry Wogan.

His career has spanned more than five decades and includes the chat show Wogan, the Eurovision Song Contest, the quiz Blankety Blank and for many years being the host of Radio 2's breakfast show.

He says: "You have to create a kind of little club - you are not talking to an audience, you are talking to one person - and they are only half listening anyway. It's a mistake to think that everyone is clinging to your every word."

Kirsty Young's castaway is the scientist Professor Brian Cox.

In the press he's been called 'the pin-up professor' and his enormously popular TV series have been credited with creating the 'Brian Cox effect' - a surge in the number of would-be scientists applying to university. As a teenager he decided he wanted to be a rock star; he toured the world as a member of the band Dare and performed on Top of the Pops with his second group D:Ream.

He says:"I hope, we're beginning to treat ideas almost like we treated rock and roll - I hope so, it would be wonderful, wouldn't it, if ideas were the new rock and roll?"

Kirsty Young's castaway is the creator of Downton Abbey, Julian Fellowes.

He won an Oscar for his screenplay for Gosford Park and went on to write other feature films including The Young Victoria and Vanity Fair. Downton Abbey, which he created and writes, has been an enormous TV success with a huge audience. "Of course" he says, "if I had a clear understanding of why it had done so well, I would continue to write shows that attracted record viewers for the rest of my life."

Kirsty Young's castaway is the journalist and former editor Eve Pollard.

She was groomed for success by Rupert Murdoch, but made an editor by Robert Maxwell. Her career has spanned glossy magazines and tabloid journalism, breakfast television, biographies and novels. When she first worked on Fleet Street, she says, women were such a rarity that the male reporters didn't know what to make of her. "Any woman who has a high flying job, they don't know who to compare you to - you're not their mum, you're not their sister, you're not their wife - so they make you a sort of monster-nanny figure."
