Morgan Spurlock directs the big-screen biopic that follows boy band members Liam Payne (from Wolverhampton), Louis Tomlinson (from Doncaster), Niall Horan (from Ireland), Harry Styles (from Cheshire) and Zayn Malik (from Bradford) on stage, backstage, at home and abroad.

Mentored by Simon Cowell after dazzling audiences on the U.K. version of The X Factor, the proud "papa" of the group was there to support his boys, saying, "You know what? There is no formula; people think it's easy, it's not. You've got to find talented people. ... I felt that the fans wanted to see a bit more of the group, and that was the whole reason we made the movie."
