One Direction's 'This is Us' movie premieres

>>> WELCOME BACK TO CNN. HAPPENING RIGHT NOW IN LONDON, THE WORLD PREMIER OF ONE DIRECTION, THE MOVIE. IF YOU HAVE A TEENAGER YOU KNOW THAT ONE DIRECTION IS THE HOTTEST BOY BAND IN THE WORLD. FANS LINED UP FOR HOURS WHICH WAS DIRECTED BY OUR OWN MORGAN SPURLOCK. I KNOW THEY'RE A HUGE FAVORITE OF YOURS. I HEAR IT'S LOUD. WHAT'S GOING ON OVER THERE? >> O-M-G. THEY'VE ARRIVED HERE JUST MOMENTS AGO AND EVERYONE BEHIND ME, 17,000 SCREAMING FANS HAVE GONE TOTALLY NUTS. MANY OF THEM HAVE BEEN HERE FOR UP TO THREE DAYS. THEY HAVE BOOKS OUT, PAPERS JUST WAITING FOR THEIR AUTOGRAPHS. THE FANS FROM AROUND THE WORLD HAVE ONE FEAR RIGHT NOW AND THAT IS THEY'RE BATTERIES WILL DIE FROM THE SMARTPHONES. THERE'S A LITTLE CHARGING SECTION THERE TOO. EVERYONE IS OUT TO SEE THE WORLD PREMIER OF "THIS IS US." IT'S THE MOVIE ABOUT ONE DIRECTION. KIND OF WHAT IT'S LIKE BEHIND THE SCENES. HOW DIFFICULT IT IS FOR THEIR FAMILIES TO BE AWAY FROM THEM. WHAT THEY'RE LIKE WITH EACH. DO THEY ARGUE, DO THEY DPGET ALONG. THE MOVIE WILL START IN AN HOUR AND THE BOYS ARE HANGING OUT SIGNING AUTOGRAPHS AND THE MOVIE IS SUPPOSED TO START PRETTY SOON. IT'S TOTAL EXCITEMENT, TOTAL CHAOS AND LOADS OF FUN. >> AGAIN, I CAN'T IMAGINE WHAT THE REACTION WAS LIKE WHEN THE SINGERS SHOWED UP ON THE SCENE. IS MORGAN SPURLOCK MAKING AN EXPERIENCE THERE ON THE RED CARPET? >> THE REACTION WAS PRETTY AMAZING. IT SOUNDED LIKE AHH OVER AND OVER AGAIN. MORGAN SPURLOCK WILL BE HERE. THIS IS AN INTERESTING CHOICE FOR HIM TO MAKE. HE DID SUPER SIZE ME. WHAT HE SAID IS HE REALLY WANTED TO UNDERSTAND THE KIND OF PEOPLE MANIA BEHIND THESE GUYS. HE SAID IT WAS AN INCREDIBLE EXPERIENCE AND THEY'RE AMAZING GUYS. HE'S ON HIS WAY DOWN THE RED CARPET.
