One Direction takes their fans on their road to fame in the upcoming 3-D documentary, "This is Us," hitting theaters on Aug. 30. 

Harry Styles, Niall Horan, Zayn Malik, Liam Payne and Louis Tomlinson also show a lot of skin in the feature, according to E! Online. 

"More shirtless moments that you can imagine," said the flick's director Morgan Spurlock to an eager Directioner in a Twitter Q & A, "but how many of those make it into the final film we'll have to wait and see." 

The big screen film is chocked full of some "incredible moments" that were quite memorable. "We had some hilarious moments while filming in Japan," Spurlock posted. "It was the band's first time there and they were in awe of that city, and ROBOTS!"

There are also some special planned "Hair-iel" shots of Style's signature mane.

Directioners will get to see just how cool and adventurous the 1D boys are in real life. "They are free spirits, they do what they want, that's what makes them who they are," Spurlock added. "But we're all working hard to make a great movie."

The band also unveiled their new "Best Song Ever," which is available for download on July 22, according to the Huffington Post. 

The song scores the second half of the trailer, featuring the members "claiming that they try to stay away from the whole boy-band thing and questioning how to consume miso soup" after returning to their hometown.
