When the 3-D documentary "Justin Bieber: Never Say Never" rolled into theatres earlier this month, it seemed like the 16-year-old Canadian singer's rise to stardom had been fully covered.

Well, not exactly.

The new follow-up, "Justin Bieber: Never Say Never Director's Fan Cut," hits theatres on February 25, delivering 40 more minutes for fans to enjoy.

"A couple of weeks before the (first) movie came out we had some extra footage just lying around," director Jon Chu told CTV's Canada AM on Thursday.

"We had all these followers from Twitter and the fans online. We had to satisfy that hunger," he said.

Bieber diehards who attended screenings of "Never Say Never" may also find themselves up on the screen in this new film entry.

"If you went to a movie in Toronto or other cities you could be in it," Chu said.

This extra fan footage was pulled from cameras placed inside North American theatres for the film's opening.

The speedy release of "Director's Fan Cut" comes as no big surprise.

"Never Say Never" received fairly positive reviews from critics, particularly for its look at the building of a pop phenom in the age of social networking.

Made for US$13 million dollars, this 3D look at Bieber's road to Madison Square Garden in 2010 grossed US$30.3 million on its opening weekend.

That sum was narrowly beaten by Jennifer Aniston's romantic comedy, "Just Go With It," which grossed US$31 million.

"Never Say Never" has made more than US$53 million around the world to date. Whether Chu's "Director's Fan Cut" can exceed those numbers remains to be seen.

But the film's quality, said Chu, does not suffer from its speed delivery.

"This isn't just some DVD-worthy film," Chu said. "The film is really the way you're supposed to see it on a big screen."

Bieber's adoring fans will appreciate that and more screen time with their teen hero.

"The biggest thing I was surprised by was how genuine and honest Justin is with his fans," Chu said.

"The fans are getting smarter. They text each other about what floor he's on. But that's what I love. They're hardcore fans," he said.

Chu also loves spreading a positive message with this "Director's Fan Cut."

"The film's title goes back to Justin," Chu said.

"Everyone will tell you that you can't do this. Justin embraces being the underdog. He says ‘Yes I can.'"
