On Monday, the first official teaser trailer for Niall Horan, Harry Styles, Liam Payne, Zayn Malik and Louis Tomlinson's 3-D movie premiered. (We got a tinier glimpse last Friday on Daybreak, but this is the full 1:52 worth of 1D gloriousness.)
"I don't know if you could have more of a dramatic life change," Louis muses. "It's huge, man!"
The cameras follow the boys' rise to superstardom and their world tour. And while being the world's biggest boy band certainly has its perks, there are some downsides, too.
"The hard thing about traveling is missing home, missing family," Niall says. "But we've become literally like brothers." (Aw!)
And in another heart-wrenchingly adorable moment, Zayn tells his crying mother she needs to "get off the phone before I start crying."
The 1D 3-D flick is due out sometime in 2013.
