One Direction will get the big-screen treatment in the movie "This is Us," set to hit theaters on Aug. 30 -- and now we have a better idea of what we can expect in the upcoming flick.

A new full-length trailer shows behind-the-scenes footage, as cameras follows the guys as they return to their hometowns -- even their old jobs. Hint: one of the members used to work at a bakery.

They're seeing joking around, meeting fans and doing normal every day things. In one scene, they're figuring out eat miso soup. As they say, they're "five normal guys just having the time of their life."

To coincide with the upcoming movie, One Direction will release a new single called "Best Song Ever," officially due out later this month. Watch their announcement here, and check out the "This is Us" movie trailer below:
