As they count down the days until One Direction release their 3-D film on August 30, 2013, fans might be wondering what they can expect. With Morgan Spurlock directing, could it mean the fivesome gorge themselves on fast food?

When MTV News caught up with the guys, they joked the film may pay homage to the Spurlock’s famed 2004 documentary, “Super Size Me,” in which the filmmaker ate McDonald’s for 30 days straight. Liam Payne teased, “That’s going to be part of the film. Eating McDonald’s onstage for 30 days.”

All joking aside, the guys do know that the film will take fans on and off-stage with them, allowing unprecedented access to the global super stars. “Morgan works well because like you said, he did a lot of documentary movies,” Niall said. “That’s more so what we want our movie to be. It’s going to be a concert movie, but with a documentary side than concert side so we wanted to give it like get our personalities across because the fans know us, but we want them to know us deeper.”

Liam added, “I think he’s come up with a lot of interesting concepts and stuff for films, so it’s just going to be really exciting to work with him and see what he comes out of the bag with for us.”

The anticipation for the release is also high for the guys, who hope to use the flick as a time capsule capturing this moment in their lives. “And, also, it’s going to be amazing for us to look on in like however many years and just be like ‘This is when I was a lad’,” Louis shared, with Liam adding, “You know what we always say, when we left home to do ‘X Factor’ our parents were like ‘Make sure you take loads of pictures,’ but we’ve got a film to do that for us now so we can be lazy.”

The guys also secured a close friend as the film’s producer: Ben Winston, who directed the group’s first documentary “A Year In the Making,” in 2011. “He knows us, so we’ve got a good team on the production side of stuff,” Niall said.

The band’s mentor, Simon Cowell, will also serve as a producer. When Cowell spoke to us earlier this month, he shared that the movie may feature the group, but it’ll really be about the fans.

“Well, I mean, for anyone who’s a fan of the band, you’re gonna get a chance to really see what it’s like preparing for one of these big concert tours, a lot of it is about the fans,” he said, before showing love to Spurlock. “Morgan Spurlock‘s directing. He’s cool, I met him. I think it’s going to be amazing. He was just such fan of doing it. What he gets is storytelling and he likes detail and he’s fun and the band likes him. I think he’s going to make an interesting movie.”
