Robbie Williams and Simon Cowell are some of the famous faces who will appear in a new BBC Two documentary looking at the boy band pop music phenomenon.

Hosted by Louis Theroux, a new three-part series called “Boybands Forever” is set to air this fall and will feature a number of big names from the 90s.

Also appearing on screen will be Take That manager Nigel Martin-Smith, Westlife star Brian McFadden and members of other groups such as East 17, Blue, 5ive, 911 and Damage.

Speaking about the documentary, which reportedly took over a year to produce, documentary mogul Louis told The Sun: “I couldn't be more excited about this series.”

“An epic story with a cast of stars and star-makers, involving some of the icons of modern British pop.”

With Louis Theroux as host, the new three-part series Boybands Forever is set to air in the autumn. It features a number of big names from the 90s.

The exciting new series, which also stars the likes of Louis Walsh, Daniel Glatman and Chris Herbert, is produced by Louis Theroux and his wife's production company Mindhouse.

The three episodes deal with topics such as alcohol, drugs, riots and exploitation.

He continued: “It's a gripping fable about getting everything you dream of and then it not turning out the way you imagined. It centers on a generation of young men and their managers who were incredibly successful but also incredibly vulnerable, having the time of their lives and, in some cases, crashing.”

Robbie, who will appear in the documentary, left the chart-topping band Take That in 1995.

Take That was originally formed as a five-piece in 1989 and developed into one of the most successful bands in British history with a career spanning four decades.

Robbie then went on to enjoy great chart success on his own, scoring number one singles such as “Angels,” “She's The One,” “Millennium,” and “Let Me Entertain You,” as well as countless awards.

Earlier this year, Simon Cowell revealed that he was looking for the next One Direction and had scoured the country for a new boy band.

The 64-year-old music mogul brought together Harry Styles, Louis Tomlinson, Niall Horan, Liam Payne and Zayn Malik of One Direction on “The X Factor” in 2010, which then took the pop world by storm.

Earlier this year, Simon Cowell announced that he was looking for the next One Direction and was scouring the country for a new boy band.

Speaking about the documentary, which reportedly took over a year to produce, documentary mogul Louis told The Sun: “I couldn’t be more excited about this series.

But despite intensive advertising, Simon had to give up his search because he could not find enough potential audition candidates.

Simon planned to feature the search in a Netflix documentary called The Midas Touch – but he was reportedly told to give up and accept that “the era of successful boy bands is over.”

“The Midas Touch” was originally intended to follow his search for future stars, but now it focuses on Simon as his pop dream is shattered.

An insider from The Midas Touch told the Daily Mail: “Simon was told the original idea behind the series had to be changed.”

Instead of focusing on creating a boy band with huge success, the focus is now much more on himself.

“He is frustrated by the auditions, where many of the singers are eliminated from bands that didn't make it.

“But perhaps more importantly, Simon has been told to accept that the era of successful boy bands may be over. This is devastating for him.”
