Gary Barlow and James Corden are set to embark on a road trip around the UK for a BBC One documentary.
The one-off documentary, titled When Corden Met Barlow, will see the singer and actor travel around the country visiting the places of Barlow's childhood and adult life.
Among the famous faces to appear in the show are Robbie Williams, Elton John and Chris Evans, as well as various family members and friends of the singer.
The Take That star will discuss his career, which nearly spans 25 years, with the Gavin & Stacey actor, including the quiet years and the band's successful comeback.
Charlotte Moore, controller of BBC One, commented: "BBC One brings you this special documentary starring two of Britain's biggest characters, which sees James Corden take a road trip with Gary Barlow to discover the real story of his remarkable career."
When Corden Met Barlow is expected to air later in 2014.
