Justin Bieberhas premiered a new trailer for his forthcoming flick, Believe.

JB has joined forces once again with Never Say Never director Jon M. Chu for the follow-up, in which he contemplates whether he could become the next Hollywood trainwreck.

The 19-year old also admits that he's learned from his high-profile controversies and, by the end of film, shows audiences just how far he's come since his shaggy-haired Baby days.

Speaking to MTV News US about the film, Chu explains: "This is a transition movie to me. This was about him transforming and growing."

He goes on to address some key moments in Bieber's latest big screen adventure, stating: "The spectacle of the concert is really fun. From him on the crane reaching out to his audience, to him being underwater, being chased by paparazzi, all the scenes of the adventures you get to go on in the Believe Tour are in this movie."

"It started as a concert film, but the more we were around him, the more we got to be with him when crazy stories about him were coming out. We were literally there and saw that a lot of it was just untrue."

Among the moments addressed is an altercation with the [uuid=904b7c50-60b3-49f2-8c9b-ef9ff7a97410]paparazzi in London last March[/uuid]. While discussing the incident in the film, Bieber says that "they wanted to get a reaction out of me" and "I learned from that."

Chu went on: "We felt like it was important to show what Justin was as a human being. Some of the most powerful moments in the movie have to do with him just being a normal human being like you and me."
