The Jonas Brothers did one. Hannah Montana did one. And now the cheeky lads of One Direction are doing one: a 3-D concert film in which the teen-pop superstars show us who they really are (or at least sing some songs while wearing flashy costumes).

“1D: This Is Us” is due in theaters on Aug. 30, but to whet our appetites One Direction posted a trailer online Tuesday, which you can watch below.

What have we already learned?

TIMELINE: Summer’s must see concerts

That Harry Styles knew as a kid he wanted to entertain people. That Liam Payne’s dad always told people his son could sing. And, perhaps most importantly, that at school Louis Tomlinson was “that guy that made people laugh.”

Somewhat weirdly, “This Is Us” — which appears to complement live footage with interviews and backstage shenanigans caught on tape — was directed by Morgan Spurlock of “Super Size Me.”

Maybe it was his idea to have Harry visit the bakery where one of the singer’s co-workers used to pinch his bum?
