One Direction will strip off for 3D film 'This is Us' says director Morgan Spurlock

One Direction fans will be able to see their favourite boy band half naked from every angle in their upcoming 3D film This is Us.

Director Morgan Spurlock said: “[There are] more shirtless moments than you can imagine. Now how many of those make it into the final film we’ll have to wait and see.”

The director was speaking as part of a live chat on Twitter when fans were invited to ask him questions using the hashtag #AskMorgan1D3D.

Spurlock, who directed and starred in 2004 documentary Super Size Me, in which he attempted to eat McDonald’s food for 30 days, said the One Direction boys enjoyed taunting him by eating fast food on the shoot.

“They love eating McD in front of me,” he said. But added that the band are now banned from eating burgers and chips. “On the new tour they have a trainer who’s keeping them off the Big Macs.”

One Direction: This is Us follows the boy band on tour as well as revealing more personal insights into their relationships with friends and family.

Spurlock said: “I think fans may shed a tear or two while watching. We spend a lot of down time with the band, with their families and friends. We really wanted you to see what their ‘normal’ lives are like.”

One Direction: This is Us is released 30 August.
