The last time Take That agreed to a documentary, they had nothing to lose.

It was 2005, and they'd been inactive for almost a decade. Gary Barlow and Mark Owen had lost their record contracts, Jason Orange had abandoned his acting ambitions, and Howard Donald was quietly enjoying parenthood.

Robbie Williams, still a year away from his disastrously received Rudebox album, was the only member with a significant public profile.

When he failed to show up for the film's climactic reunion, the rest of the band reacted with a mixture of hurt and total lack of surprise.

But what happened next surprised everyone.
