One of the greatest long distance runners of all time, Ethiopian Haile Gebrselassie dominated track running for years. With countless trophies to his name, the 35-year old has an unrivalled legacy; a two-time 10,000 meter Olympic Champion with 24 world records under his belt. However, his track career ended after the 2004 Olympic Games in Athens when he had to content himself with fifth place in the 10,000 meter final due to an injury . The disappointing result prompted Gebrselassie's decision to concentrate on road running. Since then he had already broken two world marathon records.

Revealed followed Gebrselassie as he faced his next big challenge of 2007: the 34th annual Berlin Marathon. He competed against 40,000 participants in an attempt to defend his title. He won the race in 2006 in a spectacular 2 hours, 5 minutes and 56 seconds, making him the 5th fastest marathon runner of all time. Last year's goal: to beat the record set by Kenyan rival Paul Tergat in Berlin 2003 and knock more than 61 seconds off his time. And this was no mean feat; Gebrselassie faced health problems earlier in the year at the London Marathon in April when he had to pull out of the race due to breathing difficulties. We joined Gebrselassie in Addis Ababa, the Ethiopian capital, his homeplace and training ground. As he prepared for Berlin, he followed a rigorous daily exercise regime: running outside of the city twice daily. Were he to run in the center of town he wouldn't get further than one block in an hour(!) because it is so crowded.

We sought to reveal a man and his country, at a significant time in his personal and national history. His eye was on the immediate prize at the Berlin marathon, but his long-term goal is set to improve the future of Ethiopia.

Shah Rukh Khan is without doubt the toast of Bollywood today. In an industry that boasts worldwide ticket sales in the billions, Shah Rukh Khan has dominated India's silver screen for over 15 years. Starring in more than 50 Hindi films, Khan's numerous accolades include 13 prestigious Filmfare awards, regarded as the "Bollywood Oscars". $300 tickets to his world dance tours sell out in minutes, he has his own wax work figure in Madame Tussaud's, London, and was awarded the Ordre des Arts et des Lettres by the French government for his "exceptional career".

This month's Revealed goes behind the scenes on Khan's latest smash hit, Om Shanti Om, where the King of Bollywood will be rehearsing and filming the final dance scene. For Khan, the pressure is mounting as this is the second major film to be released by his own production company. Not only is the scale of the production larger and more ambitious than the first, but Khan is launching newcomers in lead roles, a risky strategy in an industry heavily reliant on its star system to draw in the large crowds. Success is crucial if Khan is to build his company and join the ranks of the handful of major production houses in Mumbai. With completion nearing, Khan takes us on set in Mumbai, where we gain a unique insight into rehearsals with his choreographers, filming with director and close friend Farah Khan, set builds, hair, make-up, lights, camera and shimmies!

Khan describes his journey from penniless actor to leading light of an industry monopolized by film dynasties and insiders. In a country where there is great passion for cinema, Khan has risen to the status of a demi-god and his posters sell alongside that of monkey god Hanuman in the holy streets of Varinasi. We visit a Mumbai cinema where his most successful film has been continuously running for 12 years. Selling out every night, people are still fighting to get a ticket to watch their hero. But the true test will be in London, where Om Shanti Om becomes the first mainstream Bollywood film to have its world premiere in the industry's iconic Leicester Square.

From set build to premiere, Revealed sheds new light on the snake-hipped legend of Bollywood, King Khan.

In May, "Revealed" takes a look at an iconic band Iron Maiden, synonymous with hedonism, heavy metal and according to some, even the devil. Having survived 30 years in the business, the six members of Iron Maiden maintain that the secret to their longevity lies in their efforts to stay true to themselves and not bow to passing trends. "Revealed" joins the group on board their tour plane, Ed Force One piloted by none other than Iron Maiden's lead singer, Bruce Dickinson, before following Maiden's progress in South America where the fans prove so fanatical the band cannot leave their hotel rooms. The program provides a unique insight into life on the road and backstage with the world's most legendary heavy metal group as they take on their most ambitious world tour to date playing 23 gigs in 12 countries on the first leg alone.

He's that rare thing in horse racing - a real superstar. The Italian-born jockey's ability in the saddle, cheeky good humor, immaculate dress sense and spectacular flying dismounts, have made him a household name. But he really captured the attention of people all over the world by riding every winner on a seven-race card at Ascot on 28 September, 1996. His 'magnificent seven' cleaned out the bookies.

"It took 300 years for someone to do it, so I don't think it'll be done again in a hurry. It's nice to be the first man to do it... it's one of those days I will never forget," Dettori tells CNN of that famous achievement.

In April's edition of Revealed, Dettori gives the viewer an intimate insight into life at home in Newmarket, from spending time with the family and tending to his horses, to practicing his DJ skills on the decks! Despite the wealth and fame that comes with jockeying success, Dettori's Italian family values are clear. He prioritizes "hands-on" fatherhood.

"It's nice to see [my kids] ride, and hopefully one of them will follow in my footsteps and carry on the family tradition. I'd like one of the boys to do it, but the decision is theirs, like my father, he didn't quite push me until I was ready to be pushed, and I'll do the same with them. If they want to do it I'll do the best I can."

The champion jockey reveals the struggle and dedication it takes in maintaining his weight. We witness Dettori determined to shed every last pound on race day. An intensive workout and sauna session combine to achieve maximum weight loss through sweating, a common practice known to jockeys as 'wasting'. Dettori must stick to a strict diet for 11 months of the year - no easy feat considering his passion for food and all things culinary.

Business partner, friend and world renown chef Marco Pierre White talks to CNN about Dettori's passion for food at the launch of Frankie Dettori's cook book at the two friends' restaurant, Frankie's. While Dettori then takes us on an exclusive tour of the kitchen, Pierre-White tells us about how the restaurant was Frankie's idea: as an Italian in London, he noticed a lack of quality cuisine in a child-friendly environment. More proof that the jockey is a Mediterranean family-man at heart.

CNN follows Dettori to the Dubai World Cup, the world's richest horse race, with a purse of $6 million, the largest prize of any race in the world. The pressure is on as the creator of the event also happens to be Dettori's boss, the owner of Godolfin stables, Sheikh Mohammed bin Rashid Al Maktoum.

On this month's show, one of the world's hottest supermodels reveals a different agenda to the stereotypical clothes hanger. Liya Kebede is not just a pretty face. She's determined to use her fame to help alleviate the health problems suffered by mothers in some of the world's poorest regions. 'Revealed' showcases Kebede in the glamorous world of New York fashion and sees her journey to native Ethiopia on a World Health Organisation trip.

Born in Addis Abba, Kebede was not always thought of as a natural beauty. "I was really thin and people used to make fun of me...they never thought it was an advantage - I did whatever it took to gain weight." The story of her rise to cover-girl fame began when Gucci creative director Tom Ford handpicked the budding model for his Fall/Winter 2000 campaign. Revealed talks to Ford on what he saw in the then, unknown hopeful.

In 2003, Kebede was named the newest face of Estée Lauder cosmetics, making her the first person of color to serve as their representative in the company's 57-year history. The $3 million contract helped cement Liya's place amongst fashion's elite, allowing her to open doors for other women of color. Kebede's face quickly became hot currency in the fashion world. Her face frequently appears on the cover of major magazines from Vogue to Time, and fronts countless ad campaigns including Gap, and Dolce & Gabbana.

However, Kebede's real campaigning instinct is directed towards worldwide maternal health. Herself a mother of two, she was appointed WHO Goodwill Ambassador for Maternal, Newborn and Child Health in 2005. Kebede uses her supermodel status to bring people's attention to the millions of avoidable deaths that occur in the developing world. She continues to highlight the fact that each day on average 1600 mothers die from complications related to pregnancy and childbirth. During our time with her she organises a Teen Vogue Fashion Show and Charity Auction to raise money for medical care and support for mothers. The event is a huge success and raises $94,000 for Kebede's foundation.

From fashion shows and photo shoots to hospital visits and press conferences, Kebede takes us in to her high-profile world.

With a hugely enthusiastic public, ballet is one of the most popular performing arts in Japan. And the country's biggest and most international renowned star is the spectacularly talented dancer Tetsuya "Teddy" Kumakawa.

In Japan he has rock-star status, around the world he's known for his great technique. But it all started, 20 years ago when Kumakawa flew to London as a fifteen year old boy to study ballet at the Royal Ballet School. It was the start of a career that took the ballet world by storm. In 1989 he was promoted to soloist in the Royal Ballet and in 1993 he became the first Japanese dancer to be appointed Principal. He controversially left the Royal Ballet in 1998 to create a new company in Japan called K Ballet, taking with him five of the UK's top dancers.

‘Revealed' follows Kumakawa at a key point in his career. He is choreographing two productions in Tokyo this Autumn. We will see him at work rehearsing ‘Swan Lake' and in training as he bids to recover from a serious injury. ‘Revealed' will assess Kumakawa's dancing career and gain access to his friends and his contemporaries.

Imran Khan is the most famous Pakistani cricketer of all time. He was not only known as one of the sport's greatest all-rounders, but also one of Pakistan's most successful captains. He was declared International Cricketer of the Year in 1989-90 and led Pakistan to numerous victories worldwide, finally clinching the world cup in 1992.

There have been many Imrans over the years - Oxford graduate, party-boy friend of the Rolling Stones, devoted husband of Jemima Goldsmith, passionate fundraiser for penniless cancer victims, and now: politician and leader of the Tehrik-e-Insaff - Movement for Justice, in Pakistan.

Revealed seeks to chart the many transformations of Khan - accompanying him on a tour of Pakistan during a typical ‘week in his life'.

We will meet him in Lahore - where he was brought up in the suburbs, and developed his cricketing skills alongside his talented cousins Javed Burki and Kajid Khan - both of whom preceded Imran in going to Oxbridge and captaining Pakistan.

Lahore holds many childhood memories and family memories for Khan, not least the cancer hospital he built in 1996 in his mother's name after she herself died of cancer. Khan will show us this monumental achievement - one of the leading institutions for free cancer treatment in the world.

Over the years, Khan has shed his playboy image, and has increasingly styled himself as the champion of the Pakistani people - auctioning off his entire cricket memorabilia to fund the hospital and other philanthropic projects. The desire to improve his beloved country led Khan to form his own political movement in 1996. He has won just one seat (his own) in Parliament. Revealed is with him in the capital Islamabad as part of his campaigning for the country's next General Election.

At a time when the future of the current Pakistani cricket team is at its most uncertain, Revealed spends a week with the man who brought them a historic victory in 1992. We will ask why he has been so resistant to return to cricket to aid the ailing team. And we are certain to find a man who despite being a national hero for his prowess on the field, despite being loved for his dazzling looks, and charismatic personality, is determined to take to the political arena and leave the sport behind.

His chances of success? Says newspaper columnist Ayaz Amir, "People react with great admiration to him ... they don't react to his politics."

Revealed will see him at a crucial time as he attempts to win popularity in Pakistan but can no longer rely on his sporting skills.

On the next Revealed, CNN takes an inside look at the contemporary art world through the eyes of renowned British sculptor Rachel Whiteread. We follow Whiteread on a journey through Italy, as she opens a major retrospective at the Museo Madre in Naples and a small exhibition of recent works at the private Lorcan O'Neill Gallery in Rome. The program examines the development and impact of Whiteread's creations, while also delving into the mysterious inner workings of the art business.

Rachel Whiteread emerged on the global art scene in the late 1980s with her casts of the spaces in and around domestic objects. In 1993, she became the first woman to win the highly sought after Turner Prize for British contemporary artists. She was honoured for her concrete caste of the inside of an entire condemned house in London's East End. The project provoked both critical acclaim and public controversy, with its merits hotly debated in both the UK and international press. Since House, Whiteread has taken on a mounting string of artistic challenges, representing Britain in the 1997 Venice Biennale, designing and completing a Holocaust Memorial in Vienna and continuing to exhibit new sculpture around the world.   

Revealed begins as Whiteread takes us on a tour of the streets and waterways of East London, as the artist shares her insights on the city that is such an integral part of her work. Whiteread allows CNN to see London as she does, with her unique perspective on space, development and the marks left by human inhabitants.

Then Revealed follows Whiteread to Naples, and we go behind the scenes to see what it takes to put together a major museum exhibition. With works flown in from galleries and private collectors around the world, Whiteread struggles to install her retrospective in the face of customs' requirements, curatorial hang-ups and public protests. Revealed is there for every step of the process, from the opening of the first crates to the public reception.

We also hear from curators, staff and critics who have their own unique insights on Whiteread's art and her style of working. This is her first ever exhibition on Italian soil and critics there can be tough. Will her work stand up in the nation of Classical and Renaissance sculpture?

Arguably one of the world's greatest sushi chefs, Nobu Matsuhisa (known to the world as simply 'Nobu') has become one of the most celebrated restaurateurs of his time. His imaginative menus which combine the finest skills and ingredients of traditional Japanese cuisine, with an imaginative acceptance of Western cooking (particularly South American influences), took the glamorous Hollywood society of LA by a storm when he first opened there in 1987. The distinct and healthy menu, and friendly "local restaurant" atmosphere meant that the original restaurant Matsuhisa became a magnet for food lovers and celebrities alike.

Since then, Nobu has stretched his empire across  the world from Beverly Hills to New York City, London to Tokyo, Aspen to Milan, Las Vegas to Miami Beach. Nobu Matsuhisa now has 17 restaurants in 13 cities, and counting.

Revealed has followed Nobu over the course of an exciting new venture for him and his global chain: the Nobu InterContinental Hong Kong is the 6th Nobu to open internationally and the first in Asia outside of Japan.

We interview Richie Notar (of Studio 54 fame), Robert De Niro (Nobu's friend and business partner), Wolfgang Puck (chef proprietor of Spago), Kenny G (saxophonist and golf buddy to Nobu) and Quincy Jones (music producer, and lifelong fan of Nobu's food) about the secret to Nobu's popularity - what makes his food so special, and the atmosphere in the restaurant so tempting.
