Barlow told The Sun that he would like to make a movie about the band's history, and has decided which actors would play his bandmates.
When the X Factor judge was questioned about a Take That film, he admitted: "No-one's ever approached us about it, never.
"We've been offered musicals and talked about them for years now but never a film.
"It is one of those stories, ours, where if you wrote it down and gave it to someone they'd go, 'Well, it's a good story but it wouldn't come true'.
"It feels like 20 years of madness, but it is a good story."
The 41-year-old added: "I'd definitely have James Corden to play me - he's such a great bloke, I love him. Howard Donald always thinks he looks like Willem Dafoe, so that would be a good one.
"Jason Orange is a bit Brad Pitt. Who'd be Mark? It'd be Ant or Dec, or you could even do both.
"And probably someone like Matt Damon should take on the role of Robbie Williams."
When asked who he would want to direct the movie, Barlow said: "Someone British should definitely make it.
"I'm not that hot on films but I could see someone quite northern and funny coming up with it.
"The Scouser Willy Russell, he's done plays but he's also done films. He's the sort of guy that would be great - I think we should get him to do it."
Barlow revealed just days ago that Take That will record again in 2013.
